For example we have list of integers:
18, -13, 23, -12, 27
18 is not a negative number because it is not less than zero.
-13 is a negative number because it is less than zero.
23 is not a negative number because it is not less than zero.
-12 is a negative number because it is less than zero.
27 is not a negative number because it is not less than zero.
Consider the example:
