Return Largest numbers in Arrays, cannot pass test

General
1

hey guys,

I have reached the return largest number checkpoint, I think i have got the code almost correct as it passes first and third test but it doesn’t seem to pass the second test. Please help me find my mistake.

function largestOfFour(arr) {
  // You can do this!
  var largest=0, nArr=[] ;

  for(i=0;i<arr.length;i++)
    {
      for(j=0;j<arr[i].length;j++)
        {
          if(largest<arr[i][j])
            {
              largest=arr[i][j];
            } 
        }
      nArr.push(largest);
    }
  return nArr;
}

largestOfFour([[13, 27, 18, 26], [4, 5, 1, 3], [32, 35, 37, 39], [1000, 1001, 857, 1]]);

:slight_smile: thanks guys.

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.

Look closely at the output you get from the test that fails. There’s a hint there. :wink:

Ah yes,

the largest variable retained the largest valve from the second for loop, it needs to be reset at the beginning of the first for loop. Fantastic. thanks.

function largestOfFour(arr) {
  // You can do this!
  var largest, nArr=[] ;

  for(i=0;i<arr.length;i++)
    {
      largest =0;
      for(j=0;j<arr[i].length;j++)
        {
          if(largest<arr[i][j])
            {
              largest=arr[i][j];
            } 
          
        }
      nArr.push(largest);
    }
  return nArr;
}

largestOfFour([[13, 27, 18, 26], [4, 5, 1, 3], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
