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
trueReturn true because "leetcode" can be segmented as "leet code".
Example 2
Input
s = "applepenapple", wordDict = ["apple","pen"]Output
trueReturn true because "applepenapple" can be segmented as "apple pen apple", and you are allowed to reuse a dictionary word.
Constraints
- 1 <= s.length <= 300
- 1 <= wordDict.length <= 1000
- 1 <= wordDict[i].length <= 20
- s and wordDict[i] consist of only lowercase English letters.
- All the strings of wordDict are unique.
