" # Rectangles # Description Count the rectangles in an ASCII diagram like the one below. ```text +--+ ++ | +-++--+ | | | +--+--+ ``` The above diagram contains these 6 rectangles: ```text +-----+ | | +-----+ ``` ```text +--+ | | | | | | +--+ ``` ```text +--+ | | +--+ ``` ```text +--+ | | +--+ ``` ```text +--+ | | +--+ ``` ```text ++ ++ ``` You may assume that the input is always a proper rectangle (i.e. the length of every line equals the length of the first line). ## Instructions append You may be able to use a brute force strategy to solve this one.
