Intuition For any operation, we need to pick the smallest possible element from the second array. So, we can start by sorting the second array. Solution Run the search with two branches: Keep the current element (if increasing), add an operation. Return the minimum of these branches. For ...
【leetcode】1187. Make Array Strictly Increasing 题目如下: Given two integer arraysarr1andarr2, return the minimum number of operations (possibly zero) needed to makearr1strictly increasing. In one operation, you can choose two indices0 <= i < arr1.lengthand0 <= j < arr2.lengthand do ...
Given a 0-indexed integer array nums, return true if it can be made strictly increasing after removing exactly one element, or false otherwise. If the array is already strictly increasing, return true. The array nums is strictly increasing if nums[i - 1] < nums[i] for each index (1 <...
链接:https://leetcode-cn.com/problems/remove-one-element-to-make-the-array-strictly-increasing这道题官方给的 tag 是简单题但是一点都不简单。题意是给一个数组,如果最多删除数组中的一个数字就能使得数组整体是单调递增的话,返回 true,否则返回 false。这道题我一开始做的时候切入点就不对,我想的一直是...
An arraynumsis strictly increasing ifnums[i] < nums[i+1]for all0 <= i < nums.length - 1. An array of length1is trivially strictly increasing. Example 1: Input: nums = [1,1,1]Output: 3Explanation: You can do the following operations: 1) Increment nums[2], so nums becomes [1,...

1909. 删除一个元素使数组严格递增 - 给你一个下标从 0 开始的整数数组 nums ,如果 恰好 删除 一个 元素后,数组 严格递增 ,那么请你返回 true ,否则返回 false 。如果数组本身已经是严格递增的,请你也返回 true 。 数组 nums 是 严格递增 的定义为:对于任意下标的 1
如果做过O(n)的非降子序列,再把这道题转换过去,就会比较简单。 需要注意的是,到底是不是strictly increase 300题是要求strictly increase...
