Top 5 List App’s Behavior
When your application first launches, it shouldn’t display previous button. When user clicks to the NEXTbutton, the Number field should decrease, display different image and description or info also PREVIOUSbutton should appear. When user reaches to the end of the top list the NEXT button should disappear.
