Given a string, convert the characters of the string into opposite case, i.e. if a character is lower case than convert it into upper case and vice versa.
Examples:

Input : geeksForgEeks
Output : GEEKSfORGeEKS

Input : hello every one
Output : HELLO EVERY ONE
Recommended: Please try your approach on {IDE} first, before moving on to the solution.
ASCII values of alphabets: A – Z = 65 to 90, a – z = 97 to 122
Steps:

Take one string of any length and calculate its length.
Scan string character by character and keep checking the index .
If character in a index is in lower case, then subtract 32 to convert it in upper case, else add 32 to convert it in upper case
Print the final string.
