# Minimize Maximum Pair Sum in Array solution leetcode

## Minimize Maximum Pair Sum in Array solution leetcode

Table of Contents

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.

• For example, if we have pairs `(1,5)``(2,3)`, and `(4,4)`, the maximum pair sum would be `max(1+5, 2+3, 4+4) = max(6, 5, 8) = 8`.

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

• Each element of `nums` is in exactly one pair, and
• The maximum pair sum is minimized.

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

Minimize Maximum Pair Sum in Array solution leetcode

Example 1: Minimize Maximum Pair Sum in Array solution leetcode

```Input: nums = [3,5,2,3]
Output: 7
Explanation: The elements can be paired up into pairs (3,3) and (5,2).
The maximum pair sum is max(3+3, 5+2) = max(6, 7) = 7.
```

Example 2: Minimize Maximum Pair Sum in Array solution leetcode

```Input: nums = [3,5,4,2,4,6]
Output: 8
Explanation: The elements can be paired up into pairs (3,5), (4,4), and (6,2).
The maximum pair sum is max(3+5, 4+4, 6+2) = max(8, 8, 8) = 8.
```

Below actions are deemed contest violations

1. :

• One user submitting with multiple accounts during a contest. LCUS (leetcode.com) account and LCCN (leetcode-cn.com) account are considered to be separate accounts, even if both accounts belong to the same user.
• Multiple accounts submitting similar code for the same problem.
• Creating unwanted disturbances which interrupt other users’ participation in a contest.
• Disclosing contest solutions in public discuss posts before the end of a contest.
1. LeetCode heavily emphasizes on the justice and fairness of our contests. We have absolutely

ZERO TOLERANCE

1.  for violation behaviors (such as plagiarism, cheating, etc). When a user is deemed violating contest rules, we will apply the following penalties on this user:

• First violation: LeetCoin amount resets to zero and a contest and discuss ban for 1 month.
• Second violation: Permanent account deactivation without appeal.
Furthermore, we encourage all participants to contribute to maintaining the justice and fairness of our contest. Users who submit valid violation report(s) will earn additional LeetCoins:

• For each violating participant, the first 10 users who submit the violation report towards this participant will each earn 20 LeetCoins.
• Each user can earn up to 100 LeetCoins for reporting violations in a contest.
• Users will not be rewarded LeetCoins for reports on LCCN users.
