Hi, this is my first contribution for the Hacktoberfest.
We can convert a character to lowercase or uppercase by ASCII values. When there is an uppercase character in the string, we plus 32 because A is 65 and a is 97. a is 65 + 32 : 97. When there is a lowercase, we can minus 32 to get the uppercase.
