FreqStackhas two functions: push(int x), which pushes an integerxonto the stack. pop(), which removes and returns the most frequent element in the stack. If there is a tie for most frequent element, the element closest to the top of the stack is removed and returned. Example 1: Input...
Given an array nums of positive integers, return the longest possible length of an array prefix of nums, such that it is possible to remove exactly one element from this prefix so that every number that has appeared in it will have the same number of occurrences. If after removing one elem...
