Hi All,
I want to calculate simple HP series like 1^2 + 2^3 + 3^3....
where the raised to index can be any
e.g 1 ^4 + 2^4 + 3^4 .....

Please help me with the correct formula to do it...

How do I calculate the HP if it say: 1^11 + 2^11 + 3^11 + 4^11 + ......n^11
or if it is say: 1^21 + 2^21 + 3^21 + ......... + n^21
The question is the raised to index can be any natural No.

HELP !!!

You are going to get to some pretty big numbers pretty fast. Further, you are going to have a fairly slow program if you do it by brute force. I'd suggest finding a math textbook and see if there is some easier way to compute these values. I didn't get that far in math, so I have no idea, but there is probably something out there.

research would be your best bet at this point.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
I agree. Here's the link:
