JavaScript Mini-Max Sum-HackerRank网站的挑战 [英] JavaScript Mini-Max Sum - Challenge from HackerRank website

问题描述

这是挑战：

https://www.hackerrank.com/challenges/mini-max-sum/problem

尽管我的回答是相同的符合预期结果的数字，我做错了某件事，因为我的答案被拒绝了。
我该如何解决？

Despite my answer is returning the same number that matches the expected result, I have done something wrong because my answer has been rejected. How can I solve it?

这是我尝试过的解决方案：

Here is the solution I had tried:

function miniMaxSum(arr) {   

  var arrClone1 = arr.slice() 
  var arrClone2 = arr.slice() 

  var arrMinor = arrClone1.sort(function(a, b){return a - b;})
  arrMinor.pop()

  var arrMajor = arrClone2.sort(function(a, b){return b - a;})
  arrMajor.pop()

  function getSum(a, b) {
    return a + b;
  }

  var result1 = arrMinor.reduce(getSum) 
  var result2 = arrMajor.reduce(getSum)    

  console.log(`${result1} ${result2}`) // it is returning: 10 14 

推荐答案

我找到了答案。我注意到将函数参数命名为输入而不是 arr是强制性的。这就是为什么尽管代码返回了正确的结果，答案仍被HackerRank平台拒绝的原因

I found the answer. I noticed that was mandatory to name the function argument as 'input' instead of 'arr'. That's why the answer was rejected by the HackerRank platform despite the code returned the right result

就像这样

function miniMaxSum(input) {   //'input' not 'arr'    
  var arrClone1 = input.slice()   //'input' not 'arr'
  var arrClone2 = input.slice()   //'input' not 'arr'

//... rest of the code omitted
