A programmer has written a Python program to find and output the largest (highest) number in a list. However, the program contains a logic error on line 5.

1  numbers = [3, 8, 2, 12, 5]
2  highest = numbers
3  count = 0
4  while count < len(numbers):
5      if numbers[count] < highest:
6          highest = numbers[count]
7      count = count + 1
8  print(highest)

Describe how line 5 should be changed so that the program works correctly.
