Consider a game similar to tennis. The game can be palyed by 'N' number of players. The player has to win atleast 'M' games to win a set.

Print all the possible combination of winning set for all the payers.

Where

2 <= N

1 <= M

For Example if [A, B] are the players and

if M = 2 The player has to win atleast '2' games to win a set.

The output will be

A A

A B A

B A A

B B

B A B

A B B

if M = 3 The player has to win atleast '3' games to win a set.

The output will be

A A A

A B A A

A A B A

B A A A

B B B

B A B B

B B A B

A B B B

Given a random MxN matrix and a positive integer, recursively Your program should then find a continuous path thought the matrix starting at position 0,0 that will sum to n. Your program shouldomly move left (col -1), right(col +1), up (row -1) and down (row+1)and can only use a position once in the sum. if there is a such path in the matrix, create the path in a separate matrix with the same size, and replacing the indices used with 1 and the rest 0.
