正则表达式解题 完整代码如下：
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
while(line = await readline()){
let arr = line.match(/\d{1,}/g).sort((a, b) => b.length - a.length)
let m = arr[0].length;
console.log(arr.filter(x => x.length == m).join('') + ',' + m)
}
}()
