Answer
p=6
q=37
Working
- x.length gives the number of elements in the array which in this case is 6
- x[2] + x[5] * x[1] ⇒ 7 + 10 * 3 ⇒ 7 + 30 ⇒ 37

Define a class to accept values into an integer array of order 4 x 4 and check whether it is a DIAGONAL array or not. An array is DIAGONAL if the sum of the left diagonal elements equals the sum of the right diagonal elements. Print the appropriate message.
Example:
3 4 2 5
2 5 2 3
5 3 2 7
1 3 7 1Sum of the left diagonal element = 3 + 5 + 2 + 1 = 11
Sum of the right diagonal element = 5 + 2 + 3 + 1 = 11
