We have weather records at AtCoder Town for some consecutive three days. A string of length $3$, $S$, represents the records - if the $i$\-th character is `S`, it means it was sunny on the $i$\-th day; if that character is `R`, it means it was rainy on that day. Find the maximum number of consecutive rainy days in this period. ## Constraints * $|S| = 3$ * Each character of $S$ is `S` or `R`. ## Input Input is given from Standard Input in the following format: $S$ [samples]
