They removed TANDON!

Took me a whole night to solve the question and it turns out that it was copied! Did not expect this really. It takes a lot of hard work to arrive at a solution, please make sure the efforts don’t go in vain next time.

It took me 2 days to arrive at its solution as well. Though I didn’t submit. Fml.

I solved it for all the K but 7.
Now that it has been removed, could someone explain the divisibility criteria used for K = 7?

For k=7, we make 6-different matrices of size-49cross49, then do matrix exponentiation of each of them, after that multiply all of them to get a(0)(0)… All hard work went to vain…

All other k’s in the questions were a joke. Only thing to solve was for k=7 :stuck_out_tongue:
