How Does Merge Sort Work?
Merge sort is a recursive algorithm that continuously splits the array in half until it cannot be further divided (i.e., the array has only one element left, which is considered sorted). Then, the sorted subarrays are merged into one sorted array. This process is repeated until the entire array is sorted.
PHP Program for Merge Sort
Merge sort is a popular sorting algorithm that employs a divide-and-conquer approach to sort an array in PHP. It divides the array into smaller subarrays, sorts each subarray, and then merges the sorted subarrays back together to form the final sorted array.
