Thanks!

Nice kata!

In C, why the returning parameter is a double pointer ?

Great Kata!

Sort of yes, but in a smart way!

Nice Kata!

Nice Kata!

In C++, the "TEST" case does not work. But, the "ATTEMPT" case works!

Nice Kata! it worths more than the 6 kyu rank!

In C++, there are several spaces between words, leading and trailing spaces!

This sample test contains several spaces (dots are spaces):
jmxvtvmif..dqptm.csmhexf.q.jdvziiozxjm.sf.rzkdekb.tm.qw..qm.llkxwbmfjnulilkxkk.qdoceeu.hkpi.wopsmcuzlgkynrn.xisw.qw.lzazgfrdxhrbfdxmn.cbmtzkyr.z.z.oybgfctevwr.bzyke.qjgkauanw.rnvfmshnybnu.evzdljee.rofwajjtewgayoofxnck..tqzsba.bzkmf.ikdxlaeh.oz.megshgl...y

This sample test contains several spaces:
"jmxvtvmif dqptm csmhexf q jdvziiozxjm sf rzkdekb tm qw qm llkxwbmfjnulilkxkk qdoceeu hkpi wopsmcuzlgkynrn xisw qw lzazgfrdxhrbfdxmn cbmtzkyr z z oybgfctevwr bzyke qjgkauanw rnvfmshnybnu evzdljee rofwajjtewgayoofxnck tqzsba bzkmf ikdxlaeh oz megshgl y"

(in C++) in the description : Words are made up of lowercase letters and are separated by a single space.

I think, there is a something wrong in C++.

In C : do_test("354", "4th");
