2616. Minimize the Maximum Difference of Pairs
- Given an integer array and a number p, the task is to find p pairs of indices such that the maximum difference among the pairs is minimized.
- The approach involves sorting the array and using binary search to find the smallest possible maximum difference.
- Pairs are formed by selecting adjacent elements with the smallest difference to minimize the overall maximum difference.
- Binary search is used to efficiently determine the smallest value that allows for at least p valid pairs.
- Greedy pair formation ensures that pairs are optimally selected to meet the maximum difference criteria.
- The provided PHP code snippet showcases the implementation of the solution using binary search and greedy techniques.
- Initial checks are performed, the array is sorted, and binary search is executed to find the optimal maximum difference.
- The canFormPairs function validates if the given mid value allows forming at least p valid pairs.
- The binary search loop adjusts the search space based on the feasibility of forming enough pairs for the current mid value.
- This efficient approach combines binary search and greedy selection to minimize the maximum difference among pairs.
