Word break/word segment

Given a stringSAnd a dictionary of wordsDict, Determine ifSCan 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"leet code".

Dynamic Programming. Use a table to record 0 ~ Whether the I-1 meets the requirements. Note that the first table [0] = true, and the table length is the length of the input string plus one. Loop 0 ~ S. Length ()-1, which can only start from where Table [I] = true, because it is matched before it can be matched.

public class Solution {    public boolean wordBreak(String s, Set<String> dict) {        int strlen=s.length();        boolean [] table=new boolean[strlen+1];        table[0]=true;//begin is always true, so we can start the loop        for(int i=0;i<strlen;i++){            if(!table[i])// 0~i-1 are not words                continue;            for(String word: dict){                int len=word.length();                int end=i+len-1;                if(end>strlen-1)                    continue;                if(table[end+1])//already match at this position                    continue;                if(s.substring(i,end+1).equals(word)){                    table[end+1]=true;                }            }        }        return table[strlen];    }}
