🧩 Puzzle · Apply Merge Sort
Merge them
Merge sort's magic is the merge step: combining two already-sorted halves into one. Here are two sorted halves — repeatedly click the front card of whichever holds the smaller value, and it drops into the output. You only ever compare the two fronts, so the whole merge is a single linear walk.
Click the smaller of the two front cards (amber).
