Given an array of integers nums, sort the array in ascending order and return it. You must solve the problem without using any built-in functions in O(nlog(n)) time complexity and with the smallest space complexity possible. Example 1: Input: nums = [5,2,3,1] Output: [1,2,3,5]...
Given an array of integers nums, sort the array in ascending order. Example 1: Input: [5,2,3,1] Output: [1,2,3,5] 1. 2. Example 2: Input: [5,1,1,2,0,0] Output: [0,0,1,1,2,5] 1. 2. Note: 1 <= A.length <= 10000 ...
来自专栏 · Leetcode HOT 100 九大经典排序算法 ①归并排序 归并排序(MERGE-SORT)是建立在归并操作上的一种有效的排序算法,该算法是采用分治法(Divide and Conquer)的一个非常典型的应用。将已有序的子序列合并,得到完全有序的序列;即先使每个子序列有序,再使子序列段间有序。若将两个有序表合并成一个有序...
