Problem Description:

We will play a one-player game using a number line and N pieces. First, we place each of these pieces at some integer coordinate. Here, multiple pieces can be placed at the same coordinate. Our objective is to visit all of the M coordinates X with these pieces, by repeating the following move: Move: Choose a piece and let x be its coordinate. Put that piece at coordinate x+1 or x−1. Note that the coordinates where we initially place the pieces are already regarded as visited. Find the minimum number of moves required to achieve the objective.
