sir Don’t get it…how it will lead time complexity to n factorial (n! ) at 8:00 if we make all combinations
please explain this…

Hey @rupesh-4819
N! is the number of combinations
Say 1,2,3
Then possible combinations=3!=6
which are
1,2,3
1,3,2
2,1,3
2,3,1
3,1,2,
3,2,1

And then we check if all the conditions are met and then compute the answer
This will be brute force approach
