Yes, it can be done. Have a look at :
http://en.wikipedia.org/wiki/Modular_exponentiation
The algorithm is also mentioned in CLRS.I tried writing my own
modular-exponentiation code following CLRS but observed that python pow()
function is much more efficient.
Have a look at this problem :
a nice exercise to do can be this problem :
http://www.codechef.com/MARCH09/problems/A4/ , it deals with both cases,
first and last k digits and can be performed within O(log n)
