Modified. Top-answer and second-from-top don't pass anymore. Nevertheless they are not invalidated?!

Edit: now they are.

Note to author:

JS version still has under 500 solves so it's possible to edit the tests. ;-)

The tests for JavaScript are incomplete and are accepting incorrect submissions. For example, if we try to calculate decompose (9927447), the second-from-top submission returns the incorrect answer [ 1, 2, 3, 5, 6, 7, 88, 4455, 9927446 ], the third returns the correct answer [ 1, 3, 17, 87, 4455, 9927446 ], while the top answer causes a stack overflow!

I only discovered this after my incorrect algorithm was accepted, but the R version failed the unit tests.

A great Kata.
Challenging but quite interesting!

Thanks!

Great kata for reminding me of the knowledge about structure!
I love it !

Not very interesting...especially when you need to carefuly distuinguish z with 2...

Good kata. Try to figure out the pattern and get a formula.

But if there could be more specifications such as the detailed calculating process of finance(5), this kata will be better!

true, false removed
stdio.h,stdlib.h,string.h,stddef.h were already there
I keep sizeArray...
Thanks again!

Thanks, you really helped me a lot!

In C:

• true and false are defined in stdbool.h, no need to redefine them.
• Technically size_t is defined in stddef.h and stdio.h, stdlib.h, string.h, time.h, uchar.h, wchar.h. Some of these headers should be included.
• sizeArray sound like an array of sizes. It should be arraySize.

There's no such thing as null. The null pointer is NULL defined in stddef.h and some other headers.
