2441. Largest Positive Integer That Exists With Its Negative Easy

1/**
2 * [2441] Largest Positive Integer That Exists With Its Negative
3 *
4 * Given an integer array nums that does not contain any zeros, find the largest positive integer k such that -k also exists in the array.
5 * Return the positive integer k. If there is no such integer, return -1.
6 *  
7 * <strong class="example">Example 1:
8 * 
9 * Input: nums = [-1,2,-3,3]
10 * Output: 3
11 * Explanation: 3 is the only valid k we can find in the array.
12 * 
13 * <strong class="example">Example 2:
14 * 
15 * Input: nums = [-1,10,6,7,-7,1]
16 * Output: 7
17 * Explanation: Both 1 and 7 have their corresponding negative values in the array. 7 has a larger value.
18 * 
19 * <strong class="example">Example 3:
20 * 
21 * Input: nums = [-10,8,6,7,-2,-3]
22 * Output: -1
23 * Explanation: There is no a single valid k, we return -1.
24 * 
25 *  
26 * Constraints:
27 * 
28 * 	1 <= nums.length <= 1000
29 * 	-1000 <= nums[i] <= 1000
30 * 	nums[i] != 0
31 *
