What does "divide and conquer" mean in programming?
divide and conquer is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
An algorithm design strategy that breaks a problem into smaller subproblems of the same type, solves them recursively, and combines the results. Merge sort and quicksort are classic examples. The approach often yields O(n log n) or O(log n) time complexity.
Example
"Merge sort divides the array in half, sorts each half, then merges them — a classic divide and conquer approach."
