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
题目要求实现模糊匹配,代码如下:
class Solution {
public:
bool isMatch(const char *s, const char *p) {
bool isStar = false;
const char* s1, *p1;
while(*s && (*p || isStar)){
if((*s==*p) || (*p=='?')){
s++; p++;
}else if(*p == '*'){
isStar = true;
p++;
if(*p=='\0') return true;
s1 = s;
p1 = p;
}else{
if(!isStar) return false;
p =p1;
s = ++s1;
}
}
if(*s=='\0'){
while(*p=='*')p++;
if(*p=='\0') return true;
}
return false;
}
};
