难度:简单
给你一个数组
nums
,数组中有2n
个元素,按[x1,x2,...,xn,y1,y2,...,yn]
的格式排列。请你将数组按
[x1,y1,x2,y2,...,xn,yn]
格式重新排列,返回重排后的数组。示例 1:
输入:nums = [2,5,1,3,4,7], n = 3 输出:[2,3,5,4,1,7] 解释:由于 x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 ,所以答案为 [2,3,5,4,1,7]示例 2:
输入:nums = [1,2,3,4,4,3,2,1], n = 4 输出:[1,4,2,3,3,2,4,1]示例 3:
输入:nums = [1,1,2,2], n = 2 输出:[1,2,1,2]提示:
1 <= n <= 500
nums.length == 2n
1 <= nums[i] <= 10^3
题解:
class Solution: def shuffle(self, nums: List[int], n: int) -> List[int]: final_res = [] nums1 = nums[0:n] nums2 = nums[n:len(nums)] res = list(zip(nums1,nums2)) for i in res: for j in i: final_res.append(j) return final_res
