Word Break

Given a string `s` and a dictionary of strings `wordDict`, return `true` if `s` can be segmented into a space-separated sequence of one or more dictionary words. Note that the same word in the dictionary may be reused multiple times in the segmentation. **Example 1:** ``` Input: s = "leetcode", wordDict = ["leet","code"] Output: True Explanation: Return true because "leetcode" can be segmented as "leet code". ``` **Example 2:** ``` Input: s = "applepenapple", wordDict = ["apple","pen"] Output: True Explanation: Return true because "applepenapple" can be segmented as "apple pen apple". ``` **Example 3:** ``` Input: s = "catsandog", wordDict = ["cats","dog","sand","and","cat"] Output: False ```
