# BigInteger and project Euler

posted 4 years ago

i just solved #48

it was the easiest one so far(almost trivial) although fewer people have solved it than earlier problems which were harder for me. i credit the BigInteger class for this. i am thinking it must be harder to deal with huge numbers in other languages. any comments?

The series, 1^1 + 2^2 + 3^3 + ... + 10^10 = 10405071317.

Find the last ten digits of the series, 1^1 + 2^2 + 3^3 + ... + 1000^1000.

Yeah, that one is pretty trivial in any language that has an unlimited integer type. If you want more of a challenge, try doing it without BigInteger - or just move on to the next one .

Have a look at problem 97. That's another one that is trivial in theory with BigInteger, but you may find it will take ages that way - to get it down to a reasonable time you need to implement your own method to take advantage of the fact that it only wants the last 10 digits.
