Great, thanks! But how would you do if you have to read the input from a file?

Hello. When I ran the code, I got an OutOfBoundsException at index 9 for length 9. Everything is in order as far as I can see. What am I doing wrong?

I may be incorrect but I believe the for loop on line 25 should go from 0-1000 not 0-100 in order to initialize fathers[] correctly.

Hi! Can you describe what is M and N variables? I don't understand it.

in your code you have (int fathers[] = new int[1000];) but in the video its (int fathers[] = new int[100];)
