The frequency of an element is the number of times it occurs in an array. You are given an integer arraynumsand an integerk. In one operation, you can choose an index ofnumsand increment the element at that index by1. Returnthe maximum possible frequency of an element after performing at...
先选一个left，再选一个right， 都要变成right，看看要变多少次， 变的次数多于k，左边的挤掉掉， 一直挤呀一直挤，直到变数少于k， 变的次数少于k，继续右边变变变， 一个窗口多奇妙，怎么变都能找到。滑
[leetcode]508. Most Frequent Subtree Sum NoelYin “此面向敌” 目录 收起 题干 解释 思路 样例 开个坑记录一下写过的题吧。 题干 Given the root of a binary tree, return the most frequent subtree sum. If there is a tie, return all the values with the highest frequency in any order....
操作后的最高频元素必定可以是数组中已有的某一个元素。 提示1 解释 我们用 xi 来表示 nums 数组中下标为 i 的元素。 如果可以将数组内的一系列元素 xi1,…,xik 全部变为 y,假设这些元素中的最大值为 x,那么我们一定可以将这些数全部变成 x,此时频数不变且操作次数更少。 提示2 优先操作距离目标值最近...
Given the root of a tree, you are asked to find the most frequent subtree sum. The subtree sum of a node is defined as the sum of all the node values formed by the subtree rooted at that node (including the node itself). So what is the most frequent subtree sum value? If there ...
