In one operation, you can pick any index `i` of `word` and change `word[i]` to any lowercase English letter. Return _the **minimum** number of operations needed to remove all adjacent **almost-equal** characters from_ `word`. Two characters `a` and `b` are **almost-equal** if `a == b` or `a` and `b` are adjacent in the alphabet. **Example 1:** ``` **Input:** word = \"aaaaa\" **Output:** 2 **Explanation:** We can change word into \"a**c**a**c**a\" which does not have any adjacent almost-equal characters. It can be shown that the minimum number of operations needed to remove all adjacent almost-equal characters from word is 2. ``` **Example 2:** ``` **Input:** word = \"abddez\" **Output:** 2 **Explanation:** We can change word into \"**y**bd**o**ez\" which does not have any adjacent almost-equal characters. It can be shown that the minimum number of operations needed to remove all adjacent almost-equal characters from word is 2. ``` **Example 3:** ``` **Input:** word = \"zyxyxyz\" **Output:** 3 **Explanation:** We can change word into \"z**a**x**a**x**a**z\" which does not have any adjacent almost-equal characters. It can be shown that the minimum number of operations needed to remove all adjacent almost-equal characters from word is 3. ``` **Constraints:** `1 <= word.length <= 100` `word` consists only of lowercase English letters.",8 "test_case": [9 {10 "label": "Example 1",11 "input": "word = \"aaaaa\"",12 "output": "2 "13 },14 {15 "label": "Example 2",16 "input": "word = \"abddez\"",17 "output": "2 "18 },19 {20 "label": "Example 3",21 "input": "word = \"zyxyxyz\"",22 "output": "3 "23 }24 ],25 "constraints": [26 "1 <= word.length <= 100",27 "word consists only of lowercase English letters."28 ],29 "python_template": "class Solution(object):\n def removeAlmostEqualCharacters(self, word):\n \"\"\"\n :type word: str\n :rtype: int\n \"\"\"\n ",30 "java_template": "class Solution {\n public int removeAlmostEqualCharacters(String word) {\n \n }\n}",31 "metadata": {32 "func_name": "removeAlmostEqualCharacters"33 }34}
