Implement wildcard pattern matching with support for ‘?‘ and
‘*‘.
‘?‘ Matches any single character.
‘*‘ Matches any sequence of characters (including the empty sequence).
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", "*") → true
isMatch("aa", "a*") → true
isMatch("ab", "?*") → true
isMatch("aab", "c*a*b") → false
public class Solution {
public boolean isMatch(String str, String pattern)
{
int sLen = str.length();
int pLen = pattern.length();
int i = 0;
int j = 0;
int pStr = -1;
int pPattern = -1;
while (i < sLen)
{
if (j < pLen && (pattern.charAt(j) == '?' || pattern.charAt(j) == str.charAt(i)))
{
i++ ;
j++ ;
}
else if (j < pLen && pattern.charAt(j) == '*')
{
pStr = i;
pPattern = j;
j++ ;
}
else if (pPattern != -1)
{
pStr++ ;
i = pStr;
j = pPattern + 1;
}
else
{
return false;
}
}
while (j < pLen && pattern.charAt(j) == '*')
{
j++ ;
}
return j == pLen;
}
