Design an algorithm that accepts a stream of integers and retrieves the product of the last k integers of the stream. Implement […]

You are given a 0-indexed integer array nums, and an integer k. In one operation, you will: Take the two smallest integers x and y in nums. Remove x and y from nums. Add min(x,

You are given a 0-indexed array nums consisting of positive integers. You can choose two indices i and j, such that i != j, and the sum of digits of

Given two strings s and part, perform the following operation on s until all occurrences of the substring part are removed: Find the leftmost occurrence of the substring part and remove it from s. Return s after removing

You are given a string s. Your task is to remove all digits by doing this operation repeatedly: Delete the first digit and the closest non-digit character to

You are given two strings s1 and s2 of equal length. A string swap is an operation where you choose two indices in a string (not

Given an array of positive integers nums, return the maximum possible sum of an ascending subarray in nums. A subarray is defined as a contiguous
