290 - Word Pattern\. Easy Given a `pattern` and a string `s`, find if `s` follows the same pattern. Here **follow** means a full match, such that there is a bijection between a letter in `pattern` and a **non-empty** word in `s`. **Example 1:** **Input:** pattern = "abba", s = "dog cat cat dog" **Output:** true **Example 2:** **Input:** pattern = "abba", s = "dog cat cat fish" **Output:** false **Example 3:** **Input:** pattern = "aaaa", s = "dog cat cat dog" **Output:** false **Example 4:** **Input:** pattern = "abba", s = "dog dog dog dog" **Output:** false **Constraints:** * `1 <= pattern.length <= 300` * `pattern` contains only lower-case English letters. * `1 <= s.length <= 3000` * `s` contains only lower-case English letters and spaces `' '`. * `s` **does not contain** any leading or trailing spaces. * All the words in `s` are separated by a **single space**.
