Question

In pseudocode only Design (pseudocode) a program (name it Occurrences) to determine whether two two-dimensional arrays are equivalent or not. Two arrays are equivalent if they contain the same values in any order. The program main method defines two two-dimensional array of size 3-by-3 of type integer, and prompts the user to enter integer values to initialize the arrays. The main method calls method isEquivalent()that takes two two-dimensional arrays of integer and returns true (boolean value) if the arrays contain the same values in any order, otherwise it returns false. Hint: use a sort method from Lab 14 in developing the solution for this problem. Document your code and properly label the input prompts and the outputs as shown below. Sample run 1: Array A: 1 2 3 4 5 6 7 8 9 Array B: 1 2 3 6 5 4 7 8 9 Judgment: The arrays are equivalent.

Answer 1

Method isEquivalent(Array1, Array2):

        1. Linearize both arrays into a 1-D array.. Linearize means converting a 3x3 2-D array to 1-D array of size 9.
        2. So Array1 is linearize to LinArr1, and similarly, Array2 is linearize to LinArr2.
        3. Now sort LinArr1 & LinArr2 individually.
        4. Compare LinArr1 & LinArr2 element wise.. if they are same, then yes, the given arrays were equivalent
        5. Else, Given arrays were not equivalent.
