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.
