2239. Find Closest Number to Zero

Difficulty Topics

Description

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

Solution

find-closest-number-to-zero.py
class Solution:
    def findClosestNumber(self, nums: List[int]) -> int:
        m = float('inf')

        for x in nums:
            if abs(x) < abs(m):
                m = x
            elif abs(x) == abs(m):
                m = max(m, x)

        return m
