Picture This

We must assemble a jigsaw puzzle that contains 100 pieces. If a “move” consists of connecting two sections (even a section containing a single piece), what’s the minimum number of moves we must make to complete the puzzle?

Each move reduces the total number of sections by 1. Since we start with 100 sections and end with 1, it will take 99 moves to assemble the puzzle, no matter how we proceed.
