[LeetCode]-010-Regular_Expression_Matching

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

 public class Solution{
     public boolean isMatch(String s, String p) {
         Pattern pattern = Pattern.compile(p);
         Matcher matcher = pattern.matcher(s);
         return matcher.matches();
     }

     public static void main(String[] args){
         String param1 = "aa",param2 = ".*";
         if(args.length==2){
             param1 = args[0];
             param2 = args[1];
         }
         Solution solution = new Solution();
         boolean res = solution.isMatch(param1,param2);
         System.out.println(res);
     }
 }
