// 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.
