[LeetCode 1224] Maximum Equal Frequency Given an arraynumsof positive integers, return the longest possible length of an array prefix ofnums, such that it is possible to remove exactly one element from this pre
Given an arraynumsof positive integers, return the longest possible length of an array prefix ofnums, 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 element ...

FreqStack() constructs an empty frequency stack. void push(int val) pushes an integer val onto the top of the stack. int pop() removes and returns the most frequent element in the stack. If there is a tie for the most frequent element, the element closest to the stack's top is remov...

leetcode 895 Maximum Frequency Stack 让stack中pop出重复数量最大且最靠近顶端的元素。 很自然的数据结构不能有效解决。 求push和pop操作都为o(1)的方法!!!(忽略map操作时间) 空间换时间。 要在pop一个最大后保留顺序信息,那就决定着空间复杂度是n,怎么组织这个stack呢,一维还是二维。if you choose two ...
