1. print_board(board): 这个函数用于打印当前的游戏棋盘，包括玩家的棋子以及行号列号。

2. ai_move(board): 这个函数是AI的移动函数，它会随机选择一个可用的位置进行落子。

3. check_end(board, row, col, player): 这个函数检查游戏是否结束，包括检查玩家是否连成五子或者棋盘是否填满。

4. is_board_full(board): 这个函数检查棋盘是否已满，如果棋盘上没有空位置了，则返回True，表示平局。

5. check_win(board, row, col, player): 这个函数检查在给定的位置(row, col)下，某个玩家是否已经连成五子。

6. get_valid_input(prompt, max_value): 这个函数用于获取有效的玩家输入，确保输入的行列号在合法范围内。

7. main(): 这是游戏的主函数，负责整个游戏的流程控制，包括初始化棋盘、玩家轮流落子、检查游戏是否结束以及询问是否重新开始游戏。

总体来说，这个程序提供了一个简单的五子棋游戏，玩家可以与一个简单的AI对战。
