Merge Sort Formula
The Formula
When to use: Split a messy deck of cards in half, sort each half, then interleave them back in order.
Quick Example
What This Formula Means
A divide-and-conquer sorting algorithm that splits a list in half, sorts each half recursively, then merges the sorted halves.
Split a messy deck of cards in half, sort each half, then interleave them back in order.
Why This Formula Matters
One of the most efficient general-purpose sorting algorithms; used in many language standard libraries.
