OUTPUT:- Hello World Hi!

You are given a square matrix A of dimensions NxN and an integer X which means is an element of A, write a program to find P by performing the following table

(Use Big O to calculate the following time complexity)

Q 1  

def printPairs(array):

    for i in array:

        for j in array:

            print(str(i)+","+str(j))

Q2

def printUnorderedPairs(array):

    for i in range(0,len(array)):

        for j in range(i+1,len(array)):

            print(array[i] + "," + array[j])

#Question3

def printUnorderedPairs(arrayA, arrayB):

    for i in range(len(arrayA)):

        for j in range(len(arrayB)):

            if arrayA[i] < arrayB[j]:

                print(str(arrayA[i]) + "," + str(arrayB[j]))

arrayA = [1,2,3,4,5]

arrayB = [2,6,7,8]
