Given a string and the task is to count vowels, consonant, digits and special character in string. Special character also contains the white space.
Examples:
Input : str = "neveropen for neveropen121"
Output : Vowels: 5
Consonant: 8
Digit: 3
Special Character: 2
Input : str = " A1 B@ d adc"
Output : Vowels: 2
Consonant: 4
Digit: 1
Special Character: 6
