Problem: Takahashi participated in a contest on AtCoder.  The contest had N problems.  Takahashi made M submissions during the contest.  The i-th submission was made for the p_i-th problem and received the verdict S_i (`AC` or `WA`).  The number of Takahashi's correct answers is the number of problems on which he received an `AC` once or more.  The number of Takahashi's penalties is the sum of the following count for the problems on which he received an `AC` once or more: the number of `WA`s received before receiving an `AC` for the first time on that problem.  Find the numbers of Takahashi's correct answers and penalties.
