Question

Snakes and ladders is an ancient south Asian board game. It consists of 10X10 grid board which
contains some snakes and ladders at specific boxes/indexes. One hundred is the maximum and a must
to win score for each player. First player reaching 100 gets to win the game and is immediately
declared as first Winner.
You are required to do the following:
 Create a snake board of 10 rows and 10 columns.
 Randomly generate 09 snakes on the board. In order to generate snake you only need to know
head and tail of the snake. Make sure that both head and tail are on the board. Moreover, if
head is on row (Mi) and tail is on row (Mj) then i will always be less than j.
 Similarly, generate 09 ladders on the board.
 Print the snake board along with snakes and ladders on the screen.
 In order to start both the player need a six on the dice. Once the game is started display the
output on the dice and wait for key press (you can use getch()) before second player’s turn.
 Game will go on until one player wins the game.
 In case player lands on a snake’s head it will come down to its tail, here you need to display a
message “oops, snake got you!!!”
 In case player lands on the bottom of the leader it will climb the ladder, here you need to
display a message “you got lucky”
Note: Input validation is mandatory when reading taking input size of the board.
