How does merge sort algorithm typically operate?
Understand the Problem
The question is asking how the merge sort algorithm works, focusing on its operational principles and techniques involved in sorting a list.
Answer
Merge sort divides the array, sorts subarrays, then merges them.
Merge sort typically operates using the divide-and-conquer strategy. It divides the array into smaller subarrays, recursively sorts them, and then merges them back together into a sorted array.
Answer for screen readers
Merge sort typically operates using the divide-and-conquer strategy. It divides the array into smaller subarrays, recursively sorts them, and then merges them back together into a sorted array.
More Information
Merge sort is a stable sorting algorithm, meaning it maintains the relative order of equal elements. It's popular for its efficiency with time complexity of O(n log n) for most cases.
Tips
A common mistake is improperly merging subarrays, leading to incorrect sorting. Ensure the merging function correctly handles subarray boundaries.
