Code to _develop software using a regular expression module to process the following phone numbers.you are to extract the area code,trunk, number, and optionally an extension for each number. You may use the regular expression module in the language of your choice, please note that we covered the syntax for Perl 5 which is imitated by python 3, javascript, C++, and C#. Java, too. 800-555-1212 800 555 1212 800.555.1212 (800) 555-1212 1-800-555-1212 800-555-1212-1234 800-555-1212x1234 800-555-1212ext. 1234 1-(800) 555.1212 #1234 Reporting: Demonstrate your results by outputting the extracted information for each input number. Your report should be one page and it should be include a discussion of your use of the regular expression module..

How do compiler optimizations potentially affect variable storage and access in high-level programming languages?

Optimization is the fifth stage of the compiler that enhances the performance of code by increasing its speed and reducing the usage of resources.1) Select a portion of code written in a programming language of java  and apply four types of optimization techniques on it.2) Explain the applied techniques and their impact on the performance. Note: The word limit is 250-300 words (without considering the example of code).
