2068 - Check Whether Two Strings are Almost Equivalent\. Easy Two strings `word1` and `word2` are considered **almost equivalent** if the differences between the frequencies of each letter from `'a'` to `'z'` between `word1` and `word2` is **at most** `3`. Given two strings `word1` and `word2`, each of length `n`, return `true` _if_ `word1` _and_ `word2` _are **almost equivalent** , or_ `false` _otherwise_. The **frequency** of a letter `x` is the number of times it occurs in the string. **Example 1:** **Input:** word1 = "aaaa", word2 = "bccb" **Output:** false **Explanation:** There are 4 'a's in "aaaa" but 0 'a's in "bccb". The difference is 4, which is more than the allowed 3. **Example 2:** **Input:** word1 = "abcdeef", word2 = "abaaacc" **Output:** true **Explanation:** The differences between the frequencies of each letter in word1 and word2 are at most 3: - 'a' appears 1 time in word1 and 4 times in word2. The difference is 3. - 'b' appears 1 time in word1 and 1 time in word2. The difference is 0. - 'c' appears 1 time in word1 and 2 times in word2. The difference is 1. - 'd' appears 1 time in word1 and 0 times in word2. The difference is 1. - 'e' appears 2 times in word1 and 0 times in word2. The difference is 2. - 'f' appears 1 time in word1 and 0 times in word2. The difference is 1. **Example 3:** **Input:** word1 = "cccddabba", word2 = "babababab" **Output:** true **Explanation:** The differences between the frequencies of each letter in word1 and word2 are at most 3: - 'a' appears 2 times in word1 and 4 times in word2. The difference is 2. - 'b' appears 2 times in word1 and 5 times in word2. The difference is 3. - 'c' appears 3 times in word1 and 0 times in word2. The difference is 3. - 'd' appears 2 times in word1 and 0 times in word2. The difference is 2. **Constraints:** * `n == word1.length == word2.length` * `1 <= n <= 100` * `word1` and `word2` consist only of lowercase English letters.
