Talk:Euler problems/21 to 30

Problem #25 has a typo. The code which generates the fibonacci sequence is incorrect. As show it says:

fibs = 1 : 1 : 2 : zipWith (+) fibs ( tail fibs )

which actually generates:

1,1,2,2,3,4,5,7,9...

In fact the code should read:

fibs = 1 : 1 : zipWith (+) fibs ( tail fibs )

Which generates the correct sequence.
