1304. Find N Unique Integers Sum up to Zero

题目

Given an integer n, return any array containing n unique integers such that they add up to 0.

Example 1:

Input: n = 5
Output: [-7,-1,1,3,4]
Explanation: These arrays also are accepted [-5,-1,1,2,3] , [-3,-1,2,-2,4].

Example 2:

Input: n = 3
Output: [-1,0,1]

Example 3:

Input: n = 1
Output: [0]

Constraints:

1 <= n <= 1000

题目大意

给你一个整数 n，请你返回任意一个由 n 个各不相同的整数组成的数组，并且这 n 个数相加和为 0 。

提示：

1 <= n <= 1000

解题思路

给出一个数 n，输出一个有 n 个数的数组，里面元素之和为 0 。
简单题，简单循环即可。

代码

func sumZero(n int) []int {
	res, left, right, start := make([]int, n), 0, n-1, 1
	for left < right {
		res[left] = start
		res[right] = -start
		start++
		left = left + 1
		right = right - 1
	}
	return res
}
