Question

Given an input file name input2.txt containing two rows of numbers: 10 50 20 40 30 30 40 20 50 10 Write a program that reads the numbers in input2.txt and stores the numbers in each row in an array. For example, you can create two arrays named arrA and arrB, and arrA contains numbers in the first row (10, 20, 30, 40, 50) and arrB contains numbers in the second row (50, 40, 30, 20, 10) as in input2.txt. If the numbers in arrA and arrB are the same but in reverse order, your program should output a message indicating the reverse order relation. However, if input2.txt contains the following numbers: 10 10 or 10 10 20 20 20 15 30 30 30 10 40 40 40 30 50 50 50 10
