bf Truncate a string

```
function truncate(str, num) {
// Clear out that junk in your trunk
return str;
}
truncate('A-tisket a-tasket A green and yellow basket', 11);
```

`hint [7/7]`

```
function largestOfFour(arr) {
var results = [];
for (var n in arr) {
var largestNumber = 0;
for (var sb in arr[n]) {
if (arr[n][sb] > largestNumber) {
largestNumber = arr[n][sb];
}
}
results[n] = largestNumber;
}
return results;
}
```

- Create a variable to store the results as an array.
- Create an outer loop to iterate through the main array.
- Before going into the inner loop, create a variable to hold the largest number. This must be outside the inner loop.
- Create another for loop to work with the sub-arrays.
- Check if the element of the sub array is larger than the current largest number. If so, then save the number.
- After the inner loop, save the largest number in the variable for the results.
