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".

Solution

public class Solution {
    public boolean wordBreak(String s, List<String> wordDict) {

        boolean [] dp = new boolean[s.length() + 1];
        dp[0] = true;

        for(int i = 1; i <= s.length();i++)
            for(int j = 0;j<i;j++) {
                if(dp[j] && wordDict.contains(s.substring(j, i)))
                    dp[i] = true;
            }

        return dp[s.length()];
    }
}
