my solution :

it is simple brute force but i didn’t able to figure out why my solution gives runtime error (:

please help !

@pk301 your code’s complexity is O(2^n) and n is upto 100 that’s why you’re getting runtime error, since you cannot allocate this much memory.

thanks for your answer but n is only 10 the test case is upto 100 !
n (2 ≤ n ≤ 10)
