I don’t think you need two, nested for loops for this.
Discussion
I could have done it with only one you reckon?
Yee. There are some programming problems (like sorting) where one would need to nest loops, but this problem can be solved with just one loop. What do you think?
Give it a try!
I'll go back at it, less code is better code for sure.
Put 2 parameters in the first loop?
Backing up a second, I need some clarification. Will addFibs() be called more than once? Or will it be called only once?
Called once, with the numberOfFibs parameter specifing how many iterations of the first for loop.
