Consider a method checkReflection(List list). This method checks if the elements in the list reflect the values using the center of the list as the reference point. In more common terms, if the list elements have a palindromic order, the list does reflect.

Examples:

L1= {1,2,3} Does Not Reflect

L2= {1,2,2,1} Does Reflect

L3= {1} Does Reflect

L4= {} Does Reflect
