491. Non-decreasing Subsequences # 题目 # Given an integer array, your task is to find all the different possible increasing subsequences of the given array, and the length of an increasing subsequence should be at least 2. Example: Input: [4, 6, 7, 7]
Given an array withnintegers, your task is to check if it could become non-decreasing by modifying at most1element. 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 Explana...

Description Given the array nums, obtain a subsequence of the array whose sum of elements is strictly greater than the sum of the non included elements in such subsequence. If there are multiple solutions, return the subsequence with minimum size and if there still exist multiple solutions, retur...
elements not included (14 = 4 + 4 + 6). Therefore, the subsequence [7,6,7] is the minimal satisfying the conditions. Note the subsequence has to returned in non-decreasing order. Example 3: Input: nums = [6] Output: [6] Constraints: ...
665. Non-decreasing Array 解题方法 设置一个rat记录是否已经用完了更改次数,遍历数组,遇到nums[i] > nums[i+1]的情况时,判断是否能更改,如果不行返回false;如果行,判断nums[i-1]和nums[i+1]的大小关系,如果nums[i+1]>=nums[i-1]或者i在第0位,则设置nums[i]=nums[i+1],否则nums[i+1]=nums[i...

LeetCode 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: ...
subsequence [7,7] has the sum of its elements equal to 14 which is not strictly greater than the sum of elements not included (14 = 4 + 4 + 6). Therefore, the subsequence [7,6,7] is the minimal satisfying the conditions. Note the subsequence has to returned in non-decreasing order...
Explanation: You can't get a non-decreasing array by modify at most one element. Note: Thenbelongs to [1, 10,000]. 给定一个具有N个整型元素的数组,检查该数组是否能够通过最多改变一个元素的值,从而使得其本身变为单调非减数组,我们定义单调非减是指对于数组中的每一个有效下标i,都有 a[i] <=...
