LeetCode 2239. Find Closest Number to Zero

Given an integer array nums of size n, return the number with the value closest to 0 in nums. If there are multiple answers, return the number with the largest value.

Example 1:

Input: nums = [-4,-2,1,4,8]

Output: 1

Explanation:

The distance from -4 to 0 is |-4| = 4. 

The distance from -2 to 0 is |-2| = 2. 

The distance from 1 to 0 is |1| = 1. 

The distance from 4 to 0 is |4| = 4. 

The distance from 8 to 0 is |8| = 8. 

Thus, the closest number to 0 in the array is 1.

Example 2:

Input: nums = [2,-1,1]

Output: 1

Explanation: 

1 and -1 are both the closest numbers to 0, so 1 being larger is returned.

Constraints:

• 1 <= n <= 1000

• -105 <= nums[i] <= 105

• 我用的二维数组，所以肯定比较慢了，直接附上代码就行了。
