let input = [];

rl.on("line", function (line) {

    // let num = line.split(' ').map(Number); for one line

input.push(line.trim());

// rl.close();

}).on("close", function () {

const length = parseInt(input[0]);

const values = input[1].split(" ").map(Number);

console.log(`your length is ${length} & your arr is ${values}`);

process.exit();
