 ## 📝 Instructions:
 
-1. Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The element value in the i-th row and j-th column of the array should be i*j.
+1. Write a function `two_dimensional_array`, which takes 2 digits (x, y) as input and generates a 2-dimensional array.
 
-Note: i=0,1.., X-1; j=0,1,¡­Y-1.

-+ `c` is 50.
-+ `h` is 30.
-+ `d` would be the parameter of the function.
+2. The element value in the i-th row and j-th column of the array should be i*j (the index values).
