A 0-indexed array derived with length n is derived by computing the bitwise XOR (⊕) of adjacent values in a binary array original of length n. Specifically, for each index i in the range [0, n - 1]:If

You are given an array arr of positive integers. You are also given the array queries where queries[i] = [left, right]. For each query i compute the XOR of elements from left to right (that is, a

You are given a 0-indexed array nums of integers. A triplet of indices (i, j, k) is a mountain if:i < j < knums[i] < nums[j] and nums[k] < nums[j]Return the minimum possible sum of a mount

You are given a binary string s and an integer k. A binary string satisfies the k-constraint if either of the following conditions holds:The number of 0’s in the string is at most k.The number of 1’s

Given a string s and an integer k, return the total number of substrings of s where at least one character appears at least k times. Example 1:Input: s = “abacb”, k = 2Output: 4 Explanation:

You are given a 0-indexed array nums and a non-negative integer k. In one operation, you can do the following:Choose an index i that hasn’t been chosen before from the range [0, nums.length - 1].Repla

You are given an integer array nums and an integer k. The frequency of an element x is the number of times it occurs in an array. An array is called good if the frequency of each element in this array

You are given a digit string s that consists of digits from 0 to 9. A string is called semi-repetitive if there is at most one adjacent pair of the same digit. For example, “0010”, “002020”, “0123”, “

You are given an array nums consisting of positive integers. Starting with score = 0, apply the following algorithm: Choose the smallest integer of the array that is not marked. If there is a tie

Given a string s, return the maximum number of occurrences of any substring under the following rules:The number of unique characters in the substring must be less than or equal to maxLetters.The subs
