A python snake and ladder game for machine coding.

Problem Statement

Create a snake and ladder application. The application should take as input (from the command line or a file):

1. Number of snakes (s) followed by s lines each containing 2 numbers denoting the head and tail positions of the snake.
2. Number of ladders (l) followed by l lines each containing 2 numbers denoting the start and end positions of the ladder.
3. Number of players (p) followed by p lines each containing a name.

After taking these inputs, you should print all the moves in the form of the current player name followed by a random number between 1 to 6 denoting the die roll and the initial and final position based on the move. Format: <player_name> rolled a <dice_value> and moved from <initial_position> to <final_position>

When someone wins the game, print that the player won the game. Format: <player_name> wins the game

Rules of the game

1. The board will have 100 cells numbered from 1 to 100.
2. The game will have a six sided dice numbered from 1 to 6 and will always give a random number on rolling it.
3. Each player has a piece which is initially kept outside the board (i.e., at position 0).
4. Each player rolls the dice when their turn comes.
5. Based on the dice value, the player moves their piece forward that number of cells. Ex: If the dice value is 5 and the piece is at position 21, the player will put their piece at position 26 now (21+5).
6. A player wins if it exactly reaches the position 100 and the game ends there.
7. After the dice roll, if a piece is supposed to move outside position 100, it does not move.
8. The board also contains some snakes and ladders.
9. Each snake will have its head at some number and its tail at a smaller number.
10. Whenever a piece ends up at a position with the head of the snake, the piece should go down to the position of the tail of that snake.
11. Each ladder will have its start position at some number and end position at a larger number.
12. Whenever a piece ends up at a position with the start of the ladder, the piece should go up to the position of the end of that ladder.
13. There could be another snake/ladder at the tail of the snake or the end position of the ladder and the piece should go up/down accordingly.
14. Assumptions you can take apart from those already mentioned in rules
15. There won’t be a snake at 100.
16. There won’t be multiple snakes/ladders at the same start/head point.
17. It is possible to reach 100, i.e., it is possible to win the game.
18. Snakes and Ladders do not form an infinite loop.

Expectations

1. Make sure that you have a working and demonstrable code
2. Make sure that the code is functionally correct
3. Code should be modular and readable
4. Separation of concern should be addressed
5. Please do not write everything in a single file
6. Code should easily accommodate new requirements and minimal changes
7. There should be a main method from where the code could be easily testable
8. [Optional] Write unit tests, if possible
9. No need to create a GUI

Optional Requirements

Please do these only if you’ve time left. You can write your code such that these could be accommodated without changing your code much.

1. The game is played with a dice with the dice value could be between 1 to any input in a single move.
2. The board size can be customizable and can be taken as input before other input (snakes, ladders, players).
3. In case of more than 2 players, the game continues until only one player is left.
4. On getting max value, you get another turn and on getting 3 consecutive max values, all the three of those get cancelled.
