Lucky Tickets Advanced

Problem #110

Tags: puzzle long-numbers dynamic-programming

Who solved this?

This is an advanced version of the Lucky Tickets problem.

Values here are going to be slightly greater so that it is not possible to use direct count of sums as you probably did and some "dynamic programming" approach should be invented.

Please note that result could be long enough and some languages have no built-in abilities to store such values. E.g. with C++ neither long long nor double will do. You may prefer to switch to Python or Java temporarily, or implement "long arithmetics" representing values as arrays in such case.

input data contains two values: N - the length of the ticket number and B - the base of numeral system.
answer should contain the amount of lucky tickets.

Note: to simplify the matter, N is always even and B do not exceed 9.


input data:
22 8
