Here goes my best explanation:
Ok
So i'm assuming you know the basics of Java
I can't say i'm familiar with it. I'm currently learning c++
So by the end of this, t will be 20
Why?
Each time the first for loop iterates, the second for loop iterates too right?
p=0 q=0 t=1 //This is the first iteration. p and q are both 0, and 1 is added to t. The second for loop starts.
p=0 q=1 t=2 //This continues until q is 4. p WILL NOT iterate again until q is done with it's iterations.
p=0 q=2 t=3
p=0 q=3 t=4 //q is 4, thus ending the loop.
p=1 q=0 t=5 //p iterates once more. p is now 1, and the second loop starts again. Why? Because for each iteration of p, q iterates until it is finished.
p=1 q=1 t=6
p=1 q=2 t=7
p=1 q=3 t=8
p=2 q=0 t=9
p=2 q=1 t=10
p=2 q=2 t=11
p=2 q=3 t=12
p=3 q=0 t=13
p=3 q=1 t=14
p=3 q=2 t=15
p=3 q=3 t=16
p=4 q=0 t=17
p=4 q=1 t=18
p=4 q=2 t=19
p=4 q=3 t=20
This output was taken from me running the code itself. The comments were added by me afterwords.
