'use strict';


process.stdin.resume();
process.stdin.setEncoding('utf-8');


let inputString = '';
let currentLine = 0;


process.stdin.on('data', inputStdin => {
    inputString += inputStdin;
});


process.stdin.on('end', _ => {
    inputString = inputString.trim().split('\n').map(string => {
        return string.trim();
    });
    
    main();    
});


function readLine() {
    return inputString[currentLine++];
}


function main() {
    const inputString = readLine();
    const subString = readLine();


    let index = aqString.find(inputString, subString);
    if (isNaN(index) && index <= inputString.length) {
