    Algorithm to compute the k first and last digits of n^n

    Hello !

    I'm having trouble with this :

    I want to write an algorithm that computes the K first and K last digits of n^n.

    I know I should use some sort of combination between (a+b)^n and log(n) but I'm really striking out !

    Thank you in advance for your help!

    Hey SummerTime.

    Have you got access to a basic number theory book?

    Hi chiro,
    No I don't actually study mathematics so I don't have access. But if you could just point me in the right direction? I will try to learn from around the web.
    Thank you
