Write a Program to Find Closest Number to Zero

# 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
```

/**
 * @param {number[]} nums
 * @return {number}

 var findClosestNumber = function(nums) {
    let closestNum = nums[0];
    for(let i = 1; i < nums.length; i++){
        const num = Math.abs(nums[i]);
        const lastClosest = Math.abs(closestNum);
        if (num < lastClosest || (num === lastClosest && nums[i] > 0)){
            closestNum = nums[i];
        }
    }
    return closestNum;
};
