Nearest to Zero

Easy

A thermometer logged a few readings, readings: integers that may be negative. Find the reading closest to zero and return it. If several readings are equally close (say, -3 and 3), return the largest of them.

Example 1

readings=[-6, 3, -2, 9] → -2

-2 is closest to zero, at distance 2; 3 is at distance 3.

Example 2

readings=[-5, 5, 8] → 5

-5 and 5 are equally far from zero, so the larger one, 5, wins.

Example 3

readings=[0, -1] → 0

Constraints

1 ≤ len(readings) ≤ 1000
-10⁵ ≤ readings[i] ≤ 10⁵
