In some social platforms, there are some netizen who like to post "www". Since the string is like the grass, which contains plenty of "/" shapes, so there are also some netizen who post "grass".As a fast, smart, and convenient browser, MI Browser can recognize this kind of text and show some special effects. Specifically, given a string, MI Browser will determine the number of "/" shapes made by character "w", where "w" itself and the gap between two adjacent "w"s both give one `/` shape. If still not clear, please turn to sample input/output for more details.As a MI fan, you want to detect the relationship between the special effects and the number of "/" shapes, so the thing you should do first is to determine the number of "/" shapes by yourself.
