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.

Example 1:

Input: word = "abbcccc"

Output: 5

Explanation:

The possible strings are: "abbcccc", "abbccc", "abbcc", "abbc", and "abcccc".

Example 2:

Input: word = "abcd"

Output: 1

Explanation:

The only possible string is "abcd".

def possibleStringCount(self, word: str) -> int:
	count = 1
	for i in range(len(word)-1):
		if word[i] == word[i+1]:
			count += 1
	return count
