First two pictures are the instruction to answer picture. The question is "An IP address. An address is a group of 4 integers separated by the dot charater "."...

You are only allowed to use the following regular expression constructs in your answers: (a) Quantifiers: ,+,?, and {.. (b) Character classes: [..] (c) Grouping: (..) Note that the alternation ( I ) construct and predefined character classes ( \ d, I etc.) are NOT allowed and CANNOT be used in these questions. For each sub-question, your answer should be a single expression that detects all and only those strings described. instead of "color l colour" or "colo {,1}r, in general, compactness is measured by the number of characters used to describe the regular expression. 3 Please note that both the opening and closing parentheses, along with others, are special characters in regular expressions, and need to be escaped. That is, you need to use \ ( and V) instead of just (and). ( 2 points) An IP address. An IP address is a group of 4 integers separated by the dot character ". " (which is also a special character in regular expressions and needs to be escaped). Each integer can be one to three digits. The standard defines each integer to be in the range of 0 to 255 (inclusive) but we are going to ignore this (that is, we are allowing each integer to be in the range of 0 to 999 inclusive). For example, the IP. address of FSU's web site (www.uncfsu.edu) is "208.115.107.179
