It is a relatively basic first semester programming exercise where a console application is written to allow a user to enter their name, student id, day of the week a series of up to 10 integers. The user can then sort, search, display, edit and do statistical analysis (max, min, average) on the numbers. There are many structural and functional problems. You need to find and fix them, as well as explain your fix (mostly why it is a problem, but possibly how if it isn't obvious). Submit the fixed code along with additional comments as
