re-raised there with more details

the handling of acronyms / consecutive capital letters such as "requestHTTP" is not clear: should it be "request H T T P" or "request HTTP" ? the description should either specify it, or rule out 1-letter words

yes there is a mistake i missed, the bound of your for loop is incorrect, it refers to the length of the output, not of the input, so you loop out of bounds

oh, got it now. thank you very much!

(ok, i corrected it like you said but still crashed in the same way.)

• you are missing 1 byte for the nul-terminator there:

  char *str = calloc(strLen, sizeof(char));

• you are misunderstanding the contract of the is____() functions from <ctype.h>. the only guarantee is that they return a nonzero value if the character passes the predicate, and 0 otherwise. The nonzero value could be -42, 666, 1 etc.; it's an implementation detail that should not be relied upon. So:

  if(isupper(camelCase[i]) > 0) count++;
  

  should be:

  if(isupper(camelCase[i])) count++;
  

Everything worked with the CoreTests, but on the Random Tests it crashed: "Caught unexpected signal: 6". I printed both my input & output strings, and the output for the Random Tests is 100% correct. Don't really know what to do. (The language is C)
