01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第151题(顺位题号是665)。给定一个包含n个整数的数组,您的任务是通过修改最多1个元素来检查它是否可以变为非递减。如果array [i] <= array [i + 1],且0 <= i <n,则我们定义一个数组是非递减的。例如: 输入:[4,2,3] 输出:true 说明:可以修...
We define an array is non-decreasing ifarray[i] <= array[i + 1]holds for everyi(1 <= i < n). Example 1: 4 1 Example 2: Input: [4,2,1] Output: False Explanation: You can't get a non-decreasing array by modify at most one element. Note: Thenbelongs to [1, 10,000]. 要...
解法:如果可以修改成功,那么最终整个数组满足array[i] <= array[i + 1],因此,我们遍历数组,对于array[i] > array[i + 1]的情况我们可以修改的是array[i]或者是array[i + 1]使其满足非递减的排序;有下面两种情况; 对于array[i + 1] < array[i - 1],如果我们修改了array[i],还是不满足整个数组非...
665. Non-decreasing Array 题目: Given an array withnintegers, your task is to check if it could become non-decreasing by modifyingat most1element. We define an array is non-decreasing ifarray[i]<=array[i+1]holds for everyi(1 <= i < n). Example 1: Input: [4,2,3] Output: True...
73. 非降序数组(Non-decreasing Array) Alice it 来自专栏 · 算法笔记 一. 题目(medium) 改变数组里的一个值,实现非降序数组,也就是每个数字都比之前的数字大或者相等。二. 思路 判断前两个数字 是否都大于当前的数字,来决定改谁的值。当nums[i-1] > nums[i]时,就再看看是否 nums[i-2] > nums[i]...

Given an array with n integers, your task is to check if it could become non-decreasing by modifying at most 1 element. We define an array is non-decreasing if array[i] <= array[i + 1] holds for every i (1 <= i < n). Example 1: 代码语言:javascript 代码运行次数:0 运行 AI代...
Can you solve this real interview question? Find Maximum Non-decreasing Array Length - You are given a 0-indexed integer array nums. You can perform any number of operations, where each operation involves selecting a subarray of the array and replacing
Non-decreasingt-Dyck pathGenerating functionRiordan arrayDirect column-convex polyominoesFuss–Catalan numberWe extend the concept of non-decreasing Dyck paths to t -Dyck paths. We denote the set of non-decreasing t -Dyck paths by \\({{\\mathcal D}}_t\\) . Several classic questions studied...
Given an array ofnnintegers, with1≤ai≤1061≤ai≤106, and given queries of type(l,r)(l,r), find whether, if we delete all the elements of the array such thatl≤ai≤rl≤ai≤r, the resultant array will form a non-decreasing sequence. We need to answer these queries inO(1)O(1)...
