要求：

1、只能修改 setTimeout 到 Math.floor(Math.random() * 1000 的代码

2、不能修改 Math.floor(Math.random() * 1000

3、不能使用全局变量

function print(n){
  setTimeout(() => {
    console.log(n);
  }, Math.floor(Math.random() * 1000));
}
for(var i = 0; i < 100; i++){
  print(i);
}

修改后

function print(n){
  setTimeout((() => {
    console.log(n)
    return ()=>{}
  }).call(n,[]), Math.floor(Math.random() * 1000));
}
for(var i = 0; i < 100; i++){
  print(i);
}
