Input : GeeksforGeeks Output : True Input : Geeks4Geeks Output : False Input : null Output : False
In this article, the characters of the string are checked one by one using their ASCII values.
- Get the string
- Match the string:
- Check if the string is empty or not. If empty, return false
- Check if the string is null or not. If null, return false.
- If the string is neither empty nor null, then check the string characters one by one for alphabet using ASCII values.
- Return true if matched
