The $i$\-th character $(1 \leq i \leq 3)$ of $S$ represents the forecast for the $i$\-th day. `S`, `C`, and `R` stand for sunny, cloudy, and rainy, respectively. You will also be given a string $T$ of length $3$ representing the actual weather on those three days. The $i$\-th character $(1 \leq i \leq 3)$ of $S$ represents the actual weather on the $i$\-th day. `S`, `C`, and `R` stand for sunny, cloudy, and rainy, respectively. Print the number of days for which the forecast was correct. ## Constraints * $S$ and $T$ are strings of length $3$ each. * $S$ and $T$ consist of `S`, `C`, and `R`. ## Input Input is given from Standard Input in the following format: $S$ $T$ [samples]
