Problem Statement

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

Output

Print the maximum number of consecutive rainy days in the period.

Sample Input 1

RRS

Sample Output 1

2

We had rain on the 1-st and 2-nd days in the period. Here, the maximum number of consecutive rainy days is 2, so we should print 2.

Sample Input 2

SSS

Sample Output 2

0

It was sunny throughout the period. We had no rainy days, so we should print 0.

Sample Input 3

RSR

Sample Output 3

1

We had rain on the 1-st and 3-rd days - two "streaks" of one rainy day, so we should print 1.

Solution in C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include<stdio.h>
#include<stdlib.h>

int main(){
        long long x, k, d;
        scanf("%lld%lld%lld", &x, &k, &d);
        x=labs(x);
        printf("%d\n", x);
        long long y=x/d;
        printf("%d\n", y);
        if(y>=k){
                x-=k*d;
                printf("%lld", x);
        }else{
                x-=y*d;
                long long rem=k-y;
                if(rem%2==0){
                        printf("%lld", labs(x));
                }else{
                        x-=d;
                        printf("%lld", labs(x));
                }
        }
        return 0;
}
