Loop diagonally through two dimensional array

Question

I wrote the following code to walk half the diagonals of an array:

String[][] b = [a,b,c]
               [d,e,f]
               [g,h,i];  

public void LoopD         


        

Answer 1

Just help yourself, have a look at the indices you need to loop through:

#1 (0,0)               -> a
#2 (1,0)  (0,1)        -> bd
#3 (2,0)  (1,1)  (0,2) -> gec
#4 (2,1)  (1,2)        -> hf
#5 (2,2)               -> i

Look at the change of the indices in each iteration and create your algorithm. Not so difficult, so do your homework yourself ;)
