const readline = require('readline');
const rl=readline.createInterface({
input:process.stdin,
output:process.stdout
})
let arr=[];
rl.on('line',(line)=>{
arr.push(line)
})
rl.on('close',()=>{
let arr1=arr[0][0];
let arr2=arr[1].split(' ');
let arr3=arr[2][0];
//考虑第三行输入非0,1
if(arr3==0){
arr2=arr2.sort((a,b)=>{return a-b});
}
else if(arr3==1){
arr2=arr2.sort((a,b)=>{return b-a});
}
console.log(arr2.join(' '))
})
不难，参考HJ58
