Question

IN PYTHON WITHOUT USING: .APPEND/ .SORT/ INSERT / .SPLIT

Program 1: Design (pseudocode) and implement (source code) 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.

Sample run 2:

Array A:

    1   1   1

    1   5   6

    1   1   1

   

Array B:

    1   1   1

    1   6   6

    1   1   1

Judgment: The arrays are not equivalent.

Answer 1

Python code:

def isEquivalent(arr1,arr2,r,c):
    l1=[]
    l2=[]
    for i in range(r):
        for j in range(c):
            l1.append(arr1[i][j])
            l2.append(arr2[i][j])
    l1.sort()
    l2.sort()
    if l1==l2:
        print("The arrays are equivalent")
    else:
        print("The arrays are not equivalent")
def main():
    print("Enter the number of rows and columns in matrix : ")
    x=[int(x) for x in input().split()]
    r=x[0]
    c=x[1]
    print("Enter the integers to store in matrix1 : ")
    arr1=[[int(i) for i in input().split()] for j in range(r)]
    print("Enter the integers to store in matrix2 : ")
    arr2=[[int(i) for i in input().split()] for j in range(r)]
    isEquivalent(arr1,arr2,r,c)
  
if __name__=='__main__':
    main()
