kirza4 [7]

In python:

i = 1

lst1 = ([])

lst2 = ([])

while i <= 5:

   person1 = int(input("Enter the salary individual 1 got in year {}".format(i)))

   person2 = int(input("Enter the salary individual 1 got in year {}".format(i)))

   lst1.append(person1)

   lst2.append(person2)

   i += 1

if sum(lst1) > sum(lst2):

   print("Individual 1 has the highest salary")

else:

   print("Individual 2 has the highest salary")

This works correctly if the two individuals do not end up with the same salary overall.

codes according to the LOWER_BOUND and UPPER_BOUND characters. The parameter

characters are within the allowable bounds, false if any character is outside.*/
