In this short lesson, we'll discuss when we need to use nested loops and how to do this, you can insert
loop inside another one, like in this example here I have my main loop and here is nested one.
When do you need this?
For example, when you iterate over multidimensional array from the index standpoint to have nested
loop, you just need to put one loop inside and another the one you should have called for this and
use Brace's in the output.
You see that the first iteration of Main Loop I started I equals to zero and after that three iterations
of nested loop are performed.
Here you can see zero one and two after that.
The second iteration of Main Loop is started and again three iterations of nested loop are performed
and so on.
