Character Counting Program

Develop a program to calculate and display the total number of specific characters: lowercase English alphabets, digits (0 to 9), and white spaces (including space, tab '\t', and newline '\n') in a given input stream that ends with the character '$'.

Explanation:

The input is a continuous stream of characters, and the program should process all characters until the termination character '$' is encountered.

Input:

A stream of characters terminated by '$'

Output:

3 integers i.e. count_of_characters count_of_digits count_of_whitespaces (separated by space)

Example:

Input:

hello 123	
world$

Output:

10 3 3

Constraints:

• The input stream can contain any printable ASCII characters.
• The termination character '$' is not counted.

Note:

Ensure that your program accurately counts the specified character types and outputs them in the correct order.
