Do you need to convert the input to lowercase before comparing and sorting the characters in the input string?

I see you wrote "Laya" -> "aaly"

Answer 2

Check this documentation for ctype.h header. The header provides functions you can use to verify whether a character was alphabetical, numeric etc. Also how to tell whether the character was a lowercase or uppercase, and to convert between upper to lowercase, vice versa.

http://www.cplusplus.com/reference/cctype/

To sort the string (after converting it to lowercase), you can utilise `qsort` function, provided in stdlib.h header. You can learn how to use the function from the following reference:

https://en.cppreference.com/w/c/algorithm/qsort

Good luck! 👍
