how to use matrix exponentiation in this problem ? ( help required in speeding up solution )
ive been trying to solve this problem since yesterday night . however i could only come up with an O(d*d*k) solution.
this however wont work due to Memory and time limits.
I also looked at one of the solved solutions by rajat1603 solution link
Could someone explain how matrix exponentiation could be used in these type of problems ?
help would be greatly appreciated :D
