Your job is to create a program that verifies anything entered by the user is either a number or a letter. Once any errors have been corrected, the user's input will be output in reverse without spaces.
Steps:
Collect a sentence from the user that is a minimum of 10 characters and up to to 150 characters long, including spaces and punctuation. This action should occur until the limitations have been met.
Evaluate the string to ensure that any characters entered are either an upper case letters, lower case letter, or a number. All other characters should be discarded.
Display the following information to the user after processing is completed:
The number of remaining characters.
The remaining characters on a single line without spaces.
The remaining characters in reverse on a single line without spaces.
