Connect 4

Connect 4 is a game where two players aim to connect up their pieces to make 4 in a row. Each player takes turn to choose a column to drop their pieces. The first player to connect 4 pieces in a row wins the game. Player 1's pieces are represented by X and Player 2 by O. The game will start with player 1 first. The board dimensions is 6 x 7. Your cli game will have to prompt the user to enter the column number (1-based) that they want to place the next piece in.

Maze

You are given a map of N x M size. Walls are denoted by #, the player is denoted by X, exit denoted by @ and walkable paths are denoted by . Each turn, your game will prompt the user to enter a direction: up, down, left, right. There are a limited number of moves the player can make, and if the player uses up all the moves before reaching the exit, he is deemed to have lost. There is guaranteed to be an exit. If the player enters a direction that is not possible to walk to (such as trying to walk into a wall), that is counted as one move.

The input format is: <N> <M> <lives> followed by the map. An example input is shown below:
