题解 | #对整型数组根据标识进行降序/升序排序#

const readline = require('readline');

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

let row = 0
let arr = undefined
rl.on('line', function (line) {
    row++

    if(row === 2){
        arr = line.split(' ').map(Number)
    }else if(row === 3){
        let flag = Number(line)

        // 根据标识，进行排序
        arr.sort((a, b)=> flag? b-a : a-b)
        console.log(arr.join(' '))
    }
