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; } };
