正则控制输入为字符串，sort排序
const readline = require("readline");
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
let arr = []
rl.on("line", function (line) {
let re = /[a-zA-Z]/
if(line.match(re)){
arr.push(line)
}
});
rl.on("close", function () {
arr = arr.sort();
arr.map(c=>{
console.log(c)
})
});
