# 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
```go
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
}
```
