Tic Tac Toe Outcome Checker

This problem requires you to determine the outcome of a classic Tic Tac Toe game. You are given a 3×3 board where each cell contains either X, O, or an underscore _ representing an empty cell. Your task is to decide the game result using the following rules:

• If there exists a row, column, or either of the two main diagonals that contains three identical non-empty symbols, then that symbol is the winner.
• If the board is completely filled and there is no winner, the result is Draw.
• If the board is not completely filled and there is no winner, the result is Pending.

Note: When reading the board from input, empty cells are denoted with an underscore _, which should be treated as an empty string.

For example:

Input:
X O X
O X O
_ O X
Output:
X
