Word Break

Given a string s and a dictionary of words dict, determine if s can be segmented into a space-separated sequence of one or more dictionary words.

For example, given
s = "leetcode",
dict = ["leet", "code"].

Return true because "leetcode" can be segmented as "leet code".

Tips:

result[i] = result[i] || result[j] && wordDict.contains(sub);

Code:

public class Solution {
    public boolean wordBreak(String s, Set<String> wordDict) {
        boolean[] result = new boolean[s.length() + 1];
        result[0] = true;
        for (int i = 1; i <= s.length(); i++) {
            for (int j = 0; j < i; j++) {
                String sub = s.substring(j,i);
                result[i] = result[i] || result[j] && wordDict.contains(sub);
            }
        }
        return result[s.length()];
    }
}
