给定一个非空字符串 s 和一个包含非空单词列表的字典 wordDict,判定 s 是否可以被空格拆分为一个或多个在字典中出现的单词。

说明:

拆分时可以重复使用字典中的单词。
你可以假设字典中没有重复的单词。

示例 1:

输入: s = "leetcode", wordDict = ["leet", "code"]
输出: true
解释: 返回 true 因为 "leetcode" 可以被拆分成 "leet code"。
示例 2:

输入: s = "applepenapple", wordDict = ["apple", "pen"]
输出: true
解释: 返回 true 因为 "applepenapple" 可以被拆分成 "apple pen apple"。
     注意你可以重复使用字典中的单词。
示例 3:

输入: s = "catsandog", wordDict = ["cats", "dog", "sand", "and", "cat"]
输出: false
