Create a function that does the following (20 points) a. Takes an array of numbers b. Uses your previous function to perform the same operation using dynamic sizing. You will need to use "length()" or "size()" for this. c. Returns the manipulated array 6. Run BIG through your new function and call it newer_BIG. 5 points 7. Run small through your new function and call it new_small. 5 points 8. Compare equality new_BIG and newer BIG to see if they are equal. 10 points 9. Clear structure of code, detailed comments, and otherwise adhering to best practices. 20 points a. Use a section (%%) for each question. b. Thorough comments.
