You are given an integer array nums of length n.
For every positive integer g, we define the beauty of g as the product of g and the number of strictly increasing subsequences of nums whose greatest common divisor (GCD) is exactly g.
Return the sum of beauty values for all positive integers g.
Since the answer could be very large, return it modulo 109 + 7.

You are given an integer array nums.
Your task is to find two distinct indices i and j such that the product nums[i] * nums[j] is maximized, and the binary representations of nums[i] and nums[j] do not share any common set bits.
Return the maximum possible product of such a pair. If no such pair exists, return 0.
\n\n\n
Example 1:
\n\n\n
\n\nInput: nums = [1,2,3,4,5,6,7]
\n\nOutput: 12
\n\nExplanation:
\n\nThe best pair is 3 (011) and 4 (100). They share no set bits and 3 * 4 = 12.
Example 2:
\n\n\n
\n\nInput: nums = [5,6,4]
\n\nOutput: 0
\n\nExplanation:
\n\nEvery pair of numbers has at least one common set bit. Hence, the answer is 0.
\nExample 3:
\n\n\n
\n\nInput: nums = [64,8,32]
\n\nOutput: 2048
\n\nExplanation:
\n\nNo pair of numbers share a common bit, so the answer is the product of the two maximum elements, 64 and 32 (64 * 32 = 2048).

You are given a binary string s, and an integer k.
In one operation, you must choose exactly k different indices and flip each '0' to '1' and each '1' to '0'.
Return the minimum number of operations required to make all characters in the string equal to '1'. If it is not possible, return -1.
\n
Example 1:
\n\n\n
\n\nInput: s = "110", k = 1
\n\nOutput: 1
\n\nExplanation:
\n\n- \n\t
Example 2:
\n\n\n
\n\nInput: s = "0101", k = 3
\n\nOutput: 2
\n\nExplanation:
\n\nOne optimal set of operations choosing k = 3 indices in each operation is:
- \n\t
Thus, the minimum number of operations is 2.
\nExample 3:
\n\n\n
\n\nInput: s = "101", k = 2
\n\nOutput: -1
\n\nExplanation:
\n\nSince k = 2 and s has only one '0', it is impossible to flip exactly k indices to make all '1'. Hence, the answer is -1.

Given an m x n binary grid grid where:
- \n\t
A robot starts at the top-left corner of the grid (0, 0) and wants to reach the bottom-right corner (m - 1, n - 1). It can move only right or down. If the robot attempts to move into a mirror cell, it is reflected before entering that cell:
- \n\t
If this reflection would cause the robot to move outside the grid boundaries, the path is considered invalid and should not be counted.
Return the number of unique valid paths from (0, 0) to (m - 1, n - 1).
Since the answer may be very large, return it modulo 109 + 7.
Note: If a reflection moves the robot into a mirror cell, the robot is immediately reflected again based on the direction it used to enter that mirror: if it entered while moving right, it will be turned down; if it entered while moving down, it will be turned right. This process will continue until either the last cell is reached, the robot moves out of bounds or the robot moves to a non-mirror cell.

You are given a string s consisting of lowercase English letters and an integer k.
Your task is to construct a new string that contains only those characters from s which appear fewer than k times in the entire string. The order of characters in the new string must be the same as their order in s.
Return the resulting string. If no characters qualify, return an empty string.
\n\nNote: Every occurrence of a character that occurs fewer than k times is kept.
\n
Example 1:
\n\n\n
\n\nInput: s = "aadbbcccca", k = 3
\n\nOutput: "dbb"
\n\nExplanation:
\n\nCharacter frequencies in s:
- \n\t
Only 'd' and 'b' appear fewer than 3 times. Preserving their order, the result is "dbb".
Example 2:
\n\n\n
\n\nInput: s = "xyz", k = 2
\n\nOutput: "xyz"
\n\nExplanation:
\n\nAll characters ('x', 'y', 'z') appear exactly once, which is fewer than 2. Thus the whole string is returned.

\nrobots, distance, and walls:- \n\t
Every robot has one bullet that can either fire to the left or the right at most distance[i] meters.
A bullet destroys every wall in its path that lies within its range. Robots are fixed obstacles: if a bullet hits another robot before reaching a wall, it immediately stops at that robot and cannot continue.
\n\nReturn the maximum number of unique walls that can be destroyed by the robots.

You are given two integer arrays prices and strategy, where:
- \n\t
You are also given an even integer k, and may perform at most one modification to strategy. A modification consists of:
- \n\t
The profit is defined as the sum of strategy[i] * prices[i] across all days.
Return the maximum possible profit you can achieve.
\n\nNote: There are no constraints on budget or stock ownership, so all buy and sell operations are feasible regardless of past actions.
\n\n\n
Example 1:
\n\n\n\n\t\n\t\t
\n\n
\n\nInput: prices = [4,2,8], strategy = [-1,0,1], k = 2
\n\nOutput: 10
\n\nExplanation:
\n\n| Modification | \n\t\t\tStrategy | \n\t\t\tProfit Calculation | \n\t\t\tProfit | \n\t\t
|---|---|---|---|
| Original | \n\t\t\t[-1, 0, 1] | \n\t\t\t(-1 × 4) + (0 × 2) + (1 × 8) = -4 + 0 + 8 | \n\t\t\t4 | \n\t\t
| Modify [0, 1] | \n\t\t\t[0, 1, 1] | \n\t\t\t(0 × 4) + (1 × 2) + (1 × 8) = 0 + 2 + 8 | \n\t\t\t10 | \n\t\t
| Modify [1, 2] | \n\t\t\t[-1, 0, 1] | \n\t\t\t(-1 × 4) + (0 × 2) + (1 × 8) = -4 + 0 + 8 | \n\t\t\t4 | \n\t\t
Thus, the maximum possible profit is 10, which is achieved by modifying the subarray [0, 1]\u200b\u200b\u200b\u200b\u200b\u200b\u200b.
Example 2:

\n| Modification | \n\t\t\tStrategy | \n\t\t\tProfit Calculation | \n\t\t\tProfit | \n\t\t
|---|---|---|---|
| Original | \n\t\t\t[1, 1, 0] | \n\t\t\t(1 × 5) + (1 × 4) + (0 × 3) = 5 + 4 + 0 | \n\t\t\t9 | \n\t\t
| Modify [0, 1] | \n\t\t\t[0, 1, 0] | \n\t\t\t(0 × 5) + (1 × 4) + (0 × 3) = 0 + 4 + 0 | \n\t\t\t4 | \n\t\t
| Modify [1, 2] | \n\t\t\t[1, 0, 1] | \n\t\t\t(1 × 5) + (0 × 4) + (1 × 3) = 5 + 0 + 3 | \n\t\t\t8 | \n\t\t
Thus, the maximum possible profit is 9, which is achieved without any modification.

You are given a directed, weighted graph with n nodes labeled from 0 to n - 1, and an array edges where edges[i] = [ui, vi, wi] represents a directed edge from node ui to node vi with cost wi.
Each node ui has a switch that can be used at most once: when you arrive at ui and have not yet used its switch, you may activate it on one of its incoming edges vi → ui reverse that edge to ui → vi and immediately traverse it.
The reversal is only valid for that single move, and using a reversed edge costs 2 * wi.
Return the minimum total cost to travel from node 0 to node n - 1. If it is not possible, return -1.

You are given n × m grid and an integer k.
A sensor placed on cell (r, c) covers all cells whose Chebyshev distance from (r, c) is at most k.
The Chebyshev distance between two cells (r1, c1) and (r2, c2) is max(|r1 − r2|,|c1 − c2|).
Your task is to return the minimum number of sensors required to cover every cell of the grid.
\n\n\n
Example 1:
\n\n\n
\n\nInput: n = 5, m = 5, k = 1
\n\nOutput: 4
\n\nExplanation:
\n\nPlacing sensors at positions (0, 3), (1, 0), (3, 3), and (4, 1) ensures every cell in the grid is covered. Thus, the answer is 4.
Example 2:
\n\n\n
\n\nInput: n = 2, m = 2, k = 2
\n\nOutput: 1
\n\nExplanation:
\n\nWith k = 2, a single sensor can cover the entire 2 * 2 grid regardless of its position. Thus, the answer is 1.

You are given an integer array nums of length n, where nums is a permutation of the numbers in the range [0..n - 1].
You may swap elements at indices i and j only if nums[i] AND nums[j] == k, where AND denotes the bitwise AND operation and k is a non-negative integer.
Return the maximum value of k such that the array can be sorted in non-decreasing order using any number of such swaps. If nums is already sorted, return 0.
\n
Example 1:
\n\n\n
\n\nInput: nums = [0,3,2,1]
\n\nOutput: 1
\n\nExplanation:
\n\nChoose k = 1. Swapping nums[1] = 3 and nums[3] = 1 is allowed since nums[1] AND nums[3] == 1, resulting in a sorted permutation: [0, 1, 2, 3].
Example 2:
\n\n\n
\n\nInput: nums = [0,1,3,2]
\n\nOutput: 2
\n\nExplanation:
\n\nChoose k = 2. Swapping nums[2] = 3 and nums[3] = 2 is allowed since nums[2] AND nums[3] == 2, resulting in a sorted permutation: [0, 1, 2, 3].
Example 3:
\n\n\n
\n\nInput: nums = [3,2,1,0]
\n\nOutput: 0
\n\nExplanation:
\n\nOnly k = 0 allows sorting since no greater k allows the required swaps where nums[i] AND nums[j] == k.

You are given an m x n integer matrix grid, and three integers x, y, and k.
The integers x and y represent the row and column indices of the top-left corner of a square submatrix and the integer k represents the size (side length) of the square submatrix.
Your task is to flip the submatrix by reversing the order of its rows vertically.
\n\nReturn the updated matrix.

You are given a string s of length n and an integer array order, where order is a permutation of the numbers in the range [0, n - 1].
Starting from time t = 0, replace the character at index order[t] in s with '*' at each time step.
A substring is valid if it contains at least one '*'.
A string is active if the total number of valid substrings is greater than or equal to k.
Return the minimum time t at which the string s becomes active. If it is impossible, return -1.
\n
Example 1:
\n\n\n\n\t\n\t\t
\n\n
\n\nInput: s = "abc", order = [1,0,2], k = 2
\n\nOutput: 0
\n\nExplanation:
\n\nt | \n\t\t\torder[t] | \n\t\t\tModified s | \n\t\t\tValid Substrings | \n\t\t\tCount | \n\t\t\tActive \n\t\t\t(Count >= k) | \n\t\t
|---|---|---|---|---|---|
| 0 | \n\t\t\t1 | \n\t\t\t"a*c" | \n\t\t\t"*", "a*", "*c", "a*c" | \n\t\t\t4 | \n\t\t\tYes | \n\t\t
The string s becomes active at t = 0. Thus, the answer is 0.
Example 2:
\n\n\n\n\t\n\t\t
\n\n
\n\nInput: s = "cat", order = [0,2,1], k = 6
\n\nOutput: 2
\n\nExplanation:
\n\nt | \n\t\t\torder[t] | \n\t\t\tModified s | \n\t\t\tValid Substrings | \n\t\t\tCount | \n\t\t\tActive \n\t\t\t(Count >= k) | \n\t\t

The string s becomes active at t = 2. Thus, the answer is 2.
Example 3:
\n\n\n
\n\nInput: s = "xy", order = [0,1], k = 4
\n\nOutput: -1
\n\nExplanation:
\n\nEven after all replacements, it is impossible to obtain k = 4 valid substrings. Thus, the answer is -1.

You are given an integer array weight of length n, representing the weights of n parcels arranged in a straight line. A shipment is defined as a contiguous subarray of parcels. A shipment is considered balanced if the weight of the last parcel is strictly less than the maximum weight among all parcels in that shipment.
Select a set of non-overlapping, contiguous, balanced shipments such that each parcel appears in at most one shipment (parcels may remain unshipped).
\n\nReturn the maximum possible number of balanced shipments that can be formed.
\n\n\n
Example 1:
\n\n\n
\n\nInput: weight = [2,5,1,4,3]
\n\nOutput: 2
\n\nExplanation:
\n\nWe can form the maximum of two balanced shipments as follows:
\n\n- \n\t
It is impossible to partition the parcels to achieve more than two balanced shipments, so the answer is 2.
\nExample 2:
\n\n\n
\n\nInput: weight = [4,4]
\n\nOutput: 0
\n\nExplanation:
\n\nNo balanced shipment can be formed in this case:
\n\n- \n\t
As there is no way to form even one balanced shipment, the answer is 0.

You are given an integer array nums and an integer k.
An array is considered balanced if the value of its maximum element is at most k times the minimum element.
You may remove any number of elements from nums\u200b\u200b\u200b\u200b\u200b\u200b\u200b without making it empty.
Return the minimum number of elements to remove so that the remaining array is balanced.
\n\nNote: An array of size 1 is considered balanced as its maximum and minimum are equal, and the condition always holds true.

You are given an integer array nums.
Partition the array into three (possibly empty) subsequences A, B, and C such that every element of nums belongs to exactly one subsequence.
Your goal is to maximize the value of: XOR(A) + AND(B) + XOR(C)
where:
\n\n- \n\t
Return the maximum value achievable.
\n\nNote: If multiple partitions result in the same maximum sum, you can consider any one of them.
\n\n\n
Example 1:
\n\n\n
\n\nInput: nums = [2,3]
\n\nOutput: 5
\n\nExplanation:
\n\nOne optimal partition is:
\n\n- \n\t
The maximum value of: XOR(A) + AND(B) + XOR(C) = 3 + 2 + 0 = 5. Thus, the answer is 5.
Example 2:
\n\n\n
\n\nInput: nums = [1,3,2]
\n\nOutput: 6
\n\nExplanation:
\n\nOne optimal partition is:
\n\n- \n\t
The maximum value of: XOR(A) + AND(B) + XOR(C) = 1 + 2 + 3 = 6. Thus, the answer is 6.

You are given a string s consisting of uppercase English letters.
You are allowed to insert at most one uppercase English letter at any position (including the beginning or end) of the string.
\n\nReturn the maximum number of "LCT" subsequences that can be formed in the resulting string after at most one insertion.
\n
Example 1:
\n\n\n
\n\nInput: s = "LMCT"
\n\nOutput: 2
\n\nExplanation:
\n\nWe can insert a "L" at the beginning of the string s to make "LLMCT", which has 2 subsequences, at indices [0, 3, 4] and [1, 3, 4].
Example 2:
\n\n\n
\n\nInput: s = "LCCT"
\n\nOutput: 4
\n\nExplanation:
\n\nWe can insert a "L" at the beginning of the string s to make "LLCCT", which has 4 subsequences, at indices [0, 2, 4], [0, 3, 4], [1, 2, 4] and [1, 3, 4].
Example 3:
\n\n\n
\n\nInput: s = "L"
\n\nOutput: 0
\n\nExplanation:
\n\nSince it is not possible to obtain the subsequence "LCT" by inserting a single letter, the result is 0.

\n\n- \n\t
You are given an integer array nums.
For any positive integer x, define the following sequence:
- \n\t
This sequence will eventually reach the value 1.
\n\nThe popcount-depth of x is defined as the smallest integer d >= 0 such that pd = 1.
For example, if x = 7 (binary representation "111"). Then, the sequence is: 7 → 3 → 2 → 1, so the popcount-depth of 7 is 3.
You are also given a 2D integer array queries, where each queries[i] is either:
- \n\t
Return an integer array answer, where answer[i] is the number of indices for the ith query of type [1, l, r, k].
