this is by far the worst KATA I have seen in C. Unclear instructions, what am I supposed to do with it. Codewars please ban this guy from making more KATAs.

bro if you had used ctype.h then you should have used toupper() instead of doing the hard work.

unnecessarily long code and by the way if you have used malloc then you must have freed the memory at the end as well.

i think if you divide by an int, the result automatically gets floored (since it is positive value)
