3330. Find the Original Typed String I

Alice is attempting to type a specific string on her computer. However, she tends to be clumsy and may press a key for too long, resulting in a character being typed multiple times.

Although Alice tried to focus on her typing, she is aware that she may still have done this at most once.

You are given a string word, which represents the final output displayed on Alice’s screen.

Return the total number of possible original strings that Alice might have intended to type.

class Solution {
public:
    int possibleStringCount(string word) {
        int res = 0;
        for(int i = 1; i < word.length(); i++) {
            if(word[i] == word[i-1]) res++;
        }
        return res + 1;
    }
};
