The following program reads three positive integer numbers: x, y, and z entered by the user. It checks whether or not all the numbers are positive. Then, it calculates and prints the total and the average of the 50% of the input numbers. The result should be printed with 2 decimal points. If at least one of the input numbers is not positive, the program prints an error message. Complete the missing parts of the following code by drag and drop the appropriate statements shown below. ########################################################################################### average = total /3 print ("total = %2d average = %2d" %(total, average)) if (x>0 and y>0 and z>0): if (x>0 or y>0 or z>0): total = x*0.5 + y*0.5 + 2*0.5 X, Y, Z = (int(x), int(y), int(z)) print ("Numbers are not positive") x,y,z = (input ("Enter 3 integer numbers: ")).split() print ("total = %.2f average = %.2f" %(total, average)) else: total = y**0.5 + y**0.5 + 7**0.5
