Calculate the nth Fibonacci number.
Given n, return f where f = fib(n) and f(1) = 1, f(2) = 1, f(3) = 2, ...
Examples:
Input n = 5 Output f is 5 Input n = 7 Output f is 13
but, loop and conditional statement is forbidden
this is what I want
Very nice! At first the problem felt a bit heavy handed with all those restrictions (no "if", no "round"???) but I see now what you were going for and I like it :)
recursion of anonymous is from the blog of Loren.
the first test (checking 'for' loops, etc.) is not really doing anything...
Thank you , have fixed it.
The thing about these "don't use this don't use that" problems is that there are so many ways around such restrictions.
you are right,it inspires us to create a lot of new idea that is my purpose
