Created by Binbin Qi

The problem is from Problem 45436, https://www.mathworks.com/matlabcentral/cody/problems/45436-successive-zeros

Suppose n is the number of digits a number contains.

 12032 - is a valid n=5 digit number. But
 10023 - is defined as invalid -- because it contains two successive zeros.

Calculate the number of n-digit numbers that do not contain successive d-number of zeros.

The difference is adding more big integers to the test. Your algorithm needs to be much faster!

As with the other problem of this kind, the problem description should be "Calculate the number of n-digit numbers that do not contain successive d-number of zeros at least."
