Title: Please implement a function to match the containing '. ' and a regular expression of ' * '. The characters in the pattern '. ' Represents any one character, and ' * ' means that the preceding character can appear any time (including 0 times). In this point, a match is a string that matches all the characters of the entire pattern. For example, the string "AAA" matches the schema "A.A" and "ab*ac*a", but does not match "aa.a" and "Ab*a". Each t

It is made up of 0-9,a-f. The corresponding relationship with the 10 binary is: 0-9 corresponds to 0-9; A-f corresponds to 10-15; The number of N-ary can be expressed in 0---(N-1) for more than 9 letters A-F. Which is made up of characters: 012345679ABCDEF The number 16 in C language must begin with 0x. For example, 0x1 represents a 16 number. and 1 represents a decimal.
