3) The program should keep track of the total number of multiplications performed and the total sum of all the results, and should print out these values after the user has entered a negative number. The program should define a second function called 'is_even' that takes an integer as an argument and returns 1 if the number is even, and 0 if the number is odd. The 'multiply_by_two' function should use the 'is_even' function to determine whether the input number is even or odd, and should only perform the multiplication if the input number is even. If the input number is odd, the 'multiply_by_two' function should return 0 without performing the multiplication. For example, if the user enters the following integers: 5,4,3,6, the program should output: Number of multiplications: 2 Total sum of results: 32
