返回带空格的数字字符串中的最高和最低数字 [英] Return highest and lowest number in a string of numbers with spaces

问题描述

比方说，我有一串数字，用空格分隔，我想返回最高和最低的数字.如何在JS中使用函数最好地做到这一点?示例:

Let's say I have a string of numbers separated by spaces and I want to return the highest and lowest number. How could that best be done in JS using a function? Example:

highestAndLowest("1 2 3 4 5"); // return "5 1"

我希望两个数字都以字符串形式返回.最低的编号然后是空格，然后是最高的编号.

I would like the both numbers to be returned in a string. The lowest number first followed by a space then the highest number.

这是我到目前为止所拥有的:

Here is what I have so far:

function myFunction(str) {
    var tst = str.split(" ");
    return tst.max();
}

推荐答案

您可以使用Math.min和

You can use Math.min and Math.max, and use them in an array to return the result, try:

function highestAndLowest(numbers){
  numbers = numbers.split(" ");
  return Math.max.apply(null, numbers) + " " +  Math.min.apply(null, numbers)
}

document.write(highestAndLowest("1 2 3 4 5"))
