So hi guys I am going throught the Algorythms certification and I am kinda stuck…

I have rapidly seen the solution from the get a hint option and I see that I have understood correctly the use of 2d ARRAY etc. SO… in order to not give in and see in a detailed manner the correct answer could you gimme a hand

```
function largestOfFour(arr) {
var max;
var b = new Array(); //max array
for(let j=0;j<arr.lenght;j++){
max=-9999;
for(let i=0;i<arr[j][i].length;i++){
if (max<arr[j][i]){ max=arr[j][i];}}
b[j]=max;
}
return b;
}
largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
```
