Description
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
Solution
Python3
class Solution:
def sumZero(self, n: int) -> List[int]:
res = []
if n & 1: res.append(0)
for i in range(-1000,-1000+n//2):
res.append(i)
for i in range(1000, 1000 - n//2, -1):
res.append(i)
return res
