Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Description:
You have been asked to work out the area of number of rectangles.
The input to your function is a array of longs. If the arrays length is odd you should return void. Otherwise you should use adjacent pairs of longs to calculate the area.
For example if the input is {4,4,5,5,6,6,7,7} you should return {16, 25, 36, 49}.
