it's easy to write your own vasprintf() / asprintf() though, thanks to the following key vsnprintf() feature:

If bufsz is zero, nothing is written and buffer may be a null pointer, however the return value (number of bytes that would be written not including the null terminator) is still calculated and returned.

So vasprintf() boils down to a vsnprintf() call with 0 size, a malloc(), and a vprintf() call, with some boilerplate error handling. asprintf() is just a wrapper around vasprintf().

thank you

good

I dont even understand the statement :)

Great kata! I still can't understand how I solved it!

for better understand, the kata just asks how much s1 is needed to form s2

why this is wrong n = 103: expected [ [ 486, 10 ], [ 10, 486 ] ] to deeply equal []

what about the 3 new chickens he bout in the second year

is that an order?

when I use binary directly without p , it gives error : you must return string , can someone tell me why

can you explain this code please;
