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

Type 1: We can solve this using python very easily

Code:

r,c=map(int,input().split())
mat=[[str(ch) for ch in input().split()]for _ in range(r)]
for i in range(r*c-2):
    lis=[]
    for j in range(r):
        for k in range(c):
            if k+j==i:
                lis.append(mat[j][k])
    print(*lis[::-1])

Output:

5 5
a b c d e
f g h i j
k l m n o
p q r s t
u v w x y

a
f b
k g c
p l h d
u q m i e
v r n j
w s o
x t
