The pair sum of a pair (a,b) is equal to a + b. The maximum pair sum is the largest pair sum in a list of pairs.

\r\n\r\n\r\n\r\n

Given an array nums of even length n, pair up the elements of nums into n / 2 pairs such that:

\r\n\r\n\r\n\r\n

Return the minimized maximum pair sum after optimally pairing up the elements.

Example 1:

\r\n\r\n
\r\nInput: nums = [3,5,2,3]\r\nOutput: 7\r\nExplanation: The elements can be paired up into pairs (3,3) and (5,2).\r\nThe maximum pair sum is max(3+3, 5+2) = max(6, 7) = 7.\r\n
\r\n\r\n

Example 2:

\r\n\r\n
\r\nInput: nums = [3,5,4,2,4,6]\r\nOutput: 8\r\nExplanation: The elements can be paired up into pairs (3,5), (4,4), and (6,2).\r\nThe maximum pair sum is max(3+5, 4+4, 6+2) = max(8, 8, 8) = 8.\r\n
