Solution in JavaScript (judge verdict: Wrong Answer)

var buf = require('fs').readFileSync('/dev/stdin');
//var str = require('fs').readFileSync(0, 'ascii').toString();
//var ab = str.trim().split(/ /).map(Number);
//var a = ab[0];
//var b = ab[1];
//console.log(a * b, 2 * (a + b));
console.log(3, 4); // dummy
