    2441 - Largest Positive Integer That Exists With Its Negative.

    Easy

    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.

    Return the positive integer k. If there is no such integer, return -1.

    Example 1:

    Input: nums = -1,2,-3,3

    Output: 3

    Explanation: 3 is the only valid k we can find in the array.

    Example 2:

    Input: nums = -1,10,6,7,-7,1

    Output: 7

    Explanation: Both 1 and 7 have their corresponding negative values in the array. 7 has a larger value.

    Example 3:

    Input: nums = -10,8,6,7,-2,-3

    Output: -1

    Explanation: There is no a single valid k, we return -1.

    Constraints:

    • 1 <= nums.length <= 1000

    • -1000 <= nums[i] <= 1000

    • nums[i] != 0
