JavaScript

    for (let i = 0; i < lines.length - 2; i++) {
      const s = lines[i + 2].split(" ");
      scorce.push({

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
});
const lines = [];
rl.on("line", function (line) {
  lines.push(line);
  if (lines.length > 1 && lines.length - 2 === parseInt(lines[0])) {
    const scorce = [];
    lines
      .slice(2)
      .sort((a, b) => {
        if (lines[1] === "1") {
          return a.split(" ")[1] - b.split(" ")[1];
        } else {
          return b.split(" ")[1] - a.split(" ")[1];
        }
      })
      .forEach((item) => {
        console.log(item);
      });

    lines.splice(0, lines.length);
