@singh_hrmn
hello Harmandeep,
I have checked ur solution .it is correct but because u are using recursion its time complexity is exponential.

to optimise it use dynamic programming

thanks but this question is part of recursion and backtracking challenges. Can you tell me how to optimise this problem using recursion and backtracking only ??
