2239. Find Closest Number to Zero

Easy

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.

Solution

public class Solution {
    public int findClosestNumber(int[] nums) {
        int mini = Integer.MAX_VALUE;
        int closestNum = 0;
        for (int n : nums) {
            if (mini > Math.abs(n)) {
                mini = Math.abs(n);
                closestNum = n;
            } else if (mini == Math.abs(n) && closestNum < n) {
                closestNum = n;
            }
        }
        return closestNum;
    }
}
