I didnt understand solution approach nor did I find any good explanation for this (3)
What's the answer of this case? (2)
Can we also permute the rows? (2)
Solved easily using map. (Time Complexity : O(n*n*m) and Space Complexity : O(n*n) ) (1)
Can anyone explain this testcase (2)
For god's sake, please start using List in i/p params in place of ArrayList (1)
Why is this in simple array dp, and why so less points (1)
Should clarify that columns can be permutated independently for every row (3)
solution:-O(N*N*M) and space complexity O(M) (3)
Input bad formatting (BUT CORRECT) (1)
