Difficulty: Medium Given an array with n objects colored red, white or blue, sort them so that objects of the same color are adjacent, with the colors in the order red, white and blue. Here, we will use the integers 0, 1, and 2 to represent the color red, white, and blue respecti...
简介:Given an array with n objects colored red, white or blue, sort them in-place so that objects of the same color are adjacent, with the colors in the order red, white and blue.Here, we will use the integers 0, 1, and 2 to represent the color red, white, and blue respectively....

The values at even indices 0 and 2 are sorted in non-decreasing order. Return the array formed after rearranging the values of nums. Example 1: Input: nums = [4,1,2,3] Output: [2,3,4,1] Explanation: First, we sort the values present at odd indices (1 and 3) in non-increasing...
One element (red) is removed from the input data and inserted in-place into the sorted list with each iteration. Example 1: Input: head = [4,2,1,3] Output: [1,2,3,4] Example 2: Input: head = [-1,5,3,4,0] Output: [-1,0,3,4,5] Constraints: The number of nodes in...
这道题也可以用一次三路快排。数组分为 3 部分,第一个部分都是 0,中间部分都是 1,最后部分都是 2 。 参考代码 packageleetcodefuncsortColors(nums[]int){zero,one:=0,0fori,n:=rangenums{nums[i]=2ifn<=1{nums[one]=1one++}ifn==0{nums[zero]=0zero++}}} ...

Here, we will use the integers 0, 1, and 2 to represent the color red, white, and blue respectively. Note: You are not suppose to use the library’s sort function for this problem. click to show follow up. Follow up: A rather straight forward solution is a two-pass algorithm using...
