FreqStack 里面保存频次的 map 和相同频次 group 的 map。push 的时候动态的维护 x 的频次,并更新到对应频次的 group 中。pop 的时候对应减少频次字典里面的频次,并更新到对应频次的 group 中。 代码# Go package leetcode type FreqStack struct { freq map[int]int group map[int][]int maxfreq int } ...
Can you solve this real interview question? Maximum Frequency Stack - Design a stack-like data structure to push elements to the stack and pop the most frequent element from the stack. Implement the FreqStack class: * FreqStack() constructs an empty f
ImplementFreqStack, a class which simulates the operation of a stack-like data structure. 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...

实现FreqStack,模拟类似栈的数据结构的操作的一个类。 FreqStack 有两个函数: push(int x),将整数 x 推入栈中。 pop(),它移除并返回栈中出现最频繁的元素。 如果最频繁的元素不只一个,则移除并返回最接近栈顶的元素。 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/maximum-frequency-stack...
