Efficient Merge Sort Algorithm: Implementation And Optimizations
Merge Sort: O(n log n) time complexity & O(n) space complexity. Divide array into smaller subarrays, sort recursively, then merge back together. Optimizations include hybrid with Insertion Sort & in-place merging.
Understanding Merge Sort: A Comprehensive Guide What is Merge Sort? Merge Sort is one of the most efficient and widely-used sorting algorithms. It is a divide-and-conquer algorithm, meaning it breaks the problem into smaller subproblems, solves them independently, and then combines their solutions to solve the original problem. The main idea behind Merge Sort is to divide the input array into smaller subarrays until each subarray contains only one element. Then, these subarrays are merged back together in a sorted manner, resulting in a completely sorted array. Merge Sort is particul...
