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 ". Note that you are allowed to reuse a dictionary word.
Example 3:
Input: s = "catsandog ", wordDict = [ "cats ", "dog ", "sand ", "and ", "cat "] Output: false
Constraints:
1 <= s.length <= 300
1 <= wordDict.length <= 1000
1 <= wordDict[i].length <= 20
s
and wordDict[i]
consist of only lowercase English letters.wordDict
are unique.
