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") → falseisMatch("aa","aa") → trueisMatch("aaa","aa") → falseisMatch("aa", "a*") → trueisMatch("aa", ".*") → trueisMatch("ab", ".*") → trueisMatch("aab", "c*a*b") → true

bool isMatch(char* s, char* p) {    int i = 0,j = 0;    for(;s[i] != '\0' && p[j] != '\0';i++,j++){        if(p[j] == '*'){            if(p[j-1] == '.'){                if(p[j+1] == '\0') return 1;                while(s[i] != '\0' && s[i] != p[j+1]) i++;                if(s[i] = '\0') return 0;                j++;            }            else{                while(s[i] == p[j-1]) i++;                while(p[j+1] == s[i-1]) j++;                i--;            }        }        else if(p[i] != '.' && s[i] != p[j]){            if(p[j+1] != '*') return 0;            j++,i--;        }    }    if(s[j] != '\0') return 0;    if(p[j] != '\0'){        while(p[j] == )    }    return 1;}
