Problem 711. What digit is it?
The function you are being asked to write will take three numbers (n,x,q) as input. The object of the function is to determine what the qth digit (counting from the front) is of n^x.
For example, if the input is whatdigit(3,7,2), your function will need to determine the 2nd digit of 3^7. 3^7=2187, and the 2nd digit is 1. Therefore, the correct output will be y=1.
All digits will be positive integers, and there will always be at least q digits in n^x.
