Character Counting Challenge

Create a program that counts and prints the total number of specific character types from user input. Specifically, you need to count lowercase English alphabets, numeric digits (0-9), and whitespace characters (including space, tab ' ', and newline ' '). The counting should continue until the character '$' is encountered, which signals the end of input.

Input:

A continuous input stream of characters ending with '$'

Output:

Three integers representing the number of lowercase alphabets, digits, and white spaces, separated by spaces.

Example:

Suppose the input is as follows:

abc 123
	$

The output should be:

3 3 3

Constraints:

• The input stream can contain any printable ASCII character.

Note: Only implement the logic to read the input and perform the counting; the program should not print anything directly.
