Extracting words from a text

Report a typo

Write a program extracting all words that include the substring "program" from a given text. The text can be large enough. You should not count whitespaces, punctuation marks and other special characters as parts of extracted words.

Try to use Matcher and Pattern to solve it. All the needed modules are already imported. Your pattern should be case insensitive.

Input data format

A single string containing a text about programs, programmers, or programming.

Output data format

Multiple lines where each line contains two parts separated by one whitespace: the starting index of the word and the word itself.

Sample Input 1:

All Java programmers program good programs.

Sample Output 1:

9 programmers
21 program
34 programs

Write a program in Java 17

import java.util.Scanner;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

String text = scanner.nextLine();

// write your code here

}
