【入门】算法nodeJs：排序

const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void (async function () {
    // Write your code here
    n = await readline();
    const arr = (await readline()).split(" ");
    let op = Number(await readline());
    if (op) {
        console.log(arr.sort((a, b) => b - a).join(" "));
    } else {
        console.log(arr.sort((a, b) => a - b).join(" "));
    }
})();
