103. Implement a Simple Shell Command Parser

In embedded CLI (command-line interface) systems, you often need to parse commands typed by the user into tokens (like command and its arguments). A lightweight parser is used to extract each word (separated by spaces) into an array of strings.

Your task is to:

• Read a single input line (up to 100 characters)
• Split it into words separated by one or more spaces
• Print each token on a new line
• Do not use strtok() or any string library function (except gets() or scanf())

Example-1

Input:
led set 3 on

Output:
led  
set  
3  
on

Example-2

Input:
 uart   config 9600 8N1

Output:
uart  
config  
9600  
8N1

Example-3

Input:
status

Output:
status
