题解 | 单组_字符串

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

function reverseString(s) {
  return s.split('').reverse().join('');
}

void async function () {
    let n = await readline();
    let x = await readline();
    let ans = reverseString(x);
    console.log(ans);
}()

我不理解为什么要用js写这种东西
