Your goal is to determine how many "long diagonals" would be traversed in a 'length' by 'width' rectangular array, if that array was being "traversed diagonally". Examples explaining "long diagonals" and what it means to be "traversed diagonally" are provided on paper. Please refer to the paper examples and instructions. Please DO NOT write on the paper copies. You have scrap paper to write on instead. As preconditions, you may assume that 'length' and 'width' are both greater than 1. For example, if 'width' is 9 and 'length' is 4, the number of long diagonals in the traversal would be 6. If 'width' is 25 and 'length' is 24, the number of long diagonals in the traversal would be 2.
