这是悦乐书的第354次更新,第379篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第216题(顺位题号是922).给定非负整数的数组A,A中的一半整数是奇数,而剩下的一半是偶数. 对数组进行排序,以便每当A[i]为奇数时,i就是奇数; A[i]是偶数,i就是偶数. 你可以返回满足此条件的任何答案数组.例如: 输入:[4,2,5,7] 产出:[4,5,2,7] 说明:[4,7,2,5],[2,5,4,7],[2,7,4,5]也将被接受. 注意: 2 <= A.leng…

题目如下: 解题思路:非常简单的题目,引入两个变量oddInx = 1和evenInx = 0,和与A等长的结果数组res.然后遍历A,如果A[i]为偶数,则令res[evenInx] = A[i],evenInx += 2:否则令res[oddInx] = A[i],evenInx += 2. 代码如下: class Solution(object): def sortArrayByParityII(self, A): """ :type A: List[int] :rty…

Question 905. Sort Array By Parity Solution 题目大意:数组排序,偶数放前,奇数在后,偶数的数之间不用管顺序,奇数的数之间也不用管顺序 思路:建两个list,一个放偶数,一个放奇数,最后将两个list合并,转化为数组返回 Java实现: public int[] sortArrayByParity(int[] A) { List<Integer> evenList = new ArrayList<>(); List<Integer&g…
