You are given a 5x5 board containing at most 5 pieces. Your task is to move the pieces so that the cells occupied by them form a connected component. A connected component is a set of cells where each pair of cells is connected by at least one path. Consecutive cells in a path must all be adjacent. Two cells are called adjacent if they share a common edge.
You are given a String[] **board**, where the j-th character of the i-th element is '`*`' if cell (i, j) is occupied by a piece and '`.`' otherwise. Return the minimum number of moves required to achieve your goal. Each move consists of moving one piece to an adjacent empty cell. |
