Implement regular expression matching with support for '.' and '*'.
'.' Matches any single character.
'*' Matches zero or more of the preceding element.
The matching should cover the entire input string (not partial).
The function prototype should be:
bool isMatch(const char *s, const char *p)
Some examples:
isMatch("aa","a") → false
isMatch("aa","aa") → true
isMatch("aaa","aa") → false
isMatch("aa", "a*") → true
isMatch("aa", ".*") → true
isMatch("ab", ".*") → true
isMatch("aab", "c*a*b") → true
答案
public class Solution {
public boolean match(char s,char p)
{
return s==p||p=='.';
}
public boolean isMatch(String s, String p)
{
int sLen = s.length();
int pLen = p.length();
int i;
int j;
int k;
boolean[][] match = new boolean[sLen+1][pLen+1];
match[0][0]=true;
