This problem and the previous regular Expression matching a bit similar, the first reaction is the same as before, with the return to doBOOLDomatch (Char*s,Char*p) { if(*p = =' /')return*s = =' /'; if(*p = ='*') { while(*s!='

This problem is a similar regular expression match, but I found that the difficulty of the problem is more difficult than the previous problem of a few grades. As the title shows: '? ' Can match any one character, and ' * ' can match any string,

When outputting data, for simplicity, the format of the output is often not specified, and the system takes the default format based on the type of data, but sometimes you want the data to be output in a specified format, such as requiring that an

Ten. Regular Expression MatchingImplement 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)
