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]. 题...
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...
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递减,只能修改array[i + 1] 对于array[i + 1] >= array[i - 1],如果修改了array[i + 1],可能对后面的结果元素产生影响,只能修改array[i] Java class Solution { public boolean checkPossibility(int[] nums) { i...
https://leetcode.com/problems/non-decreasing-array/discuss/106826/JavaC%2B%2B-Simple-greedy-like-solution-with-explanation 用count来表示non decreasing的subarray的数量,如果是1直接return true,如果大于2直接返回false。 如果是2,说明是两段。分两种情况,第一种要求转折点index有index + 1 >= index - 1,...
Input: [4,2,1] Output: False Explanation: You can't get a non-decreasing array by modify at most one element. Note: The n belongs to [1, 10,000]. 自己琢磨的 :(简直无法忍受) 代码语言:javascript 代码运行次数:0 运行 AI代码解释 class Solution { public boolean checkPossibility(int[] nu...
First, note that the order doesn't matter so we can sort the ai in non-decreasing order. Now, note that every interval's imbalance can be calculated with its largest and smallest value. We start adding the elements to sets from smallest to largest in order. Suppose we're adding the i...
The singular value decomposition (SVD) function, applied to the correlation matrix, produces a diagonal matrix S of the same dimension as H, with nonnegative diagonal elements in decreasing order, and unitary matrices U and V so that ⁎⁎H=U⁎S⁎V'.⁎⁎H=U⁎S⁎V′ The rotat...
\end{array}$$ (58) The penalization factor p (\(p \ge 1\)) is typically taken as \(p=3\) (Sigmund 2001, 2007; Andreassen et al. 2011), and guides the problem towards a solid/void solution by penalizing intermediate density values (Bendsøe and Sigmund 1999). It should be ...
The vial was then irradiated using an LED array (λmax = 405 nm, I ~ 10 mW cm−2) for 3 h with magnetic stirring. To purify the polymersome samples, the turbid solution was removed from the light source, diluted 10 times with ddH2O and spun at 16,000g for 10...
Explanation: You can't get a non-decreasing array by modify at most one element. Note: Thenbelongs to [1, 10,000]. 这道题给了我们一个数组,说我们最多有1次修改某个数字的机会,问能不能将数组变为非递减数组。题目中给的例子太少,不能覆盖所有情况,我们再来看下面三个例子: ...
