Sum of Self Powers
Question:
A mathematician needs to sum self powers
of all the numbers up to n for a problem. Since
it would be too much hand work and calculation,
he asks for your help in creating
a program which does this operation.
To help you, he provides a simplification that
for his special formula, he doesn't need to sum all
digits but only the last d digits of each n^n;
Question: Write a program to calculate
the formula given above for the last d digits of each power.
Input specification
Two integers: n and d which will be given by the user,
1 ≤ n ≤ 10000 and 1 ≤ d ≤ 13.
Output specification
Print the last d digits, if there are 0 in the
beginning (f.e 01231321) don't print them but print
the rest of the numbers (in the previous
example simply print 1231321).

Explanation for Sample Input 1:
1^1 + 2^2 + 3^3 + 4^4 + 5^5=
1 + 4 + 27 + 256 + 125 = 413
