What This Document Is
This document represents a past examination – specifically, the first midterm – for CS 225, Data Structures and Software Principles, offered at the University of Illinois at Urbana-Champaign during the Spring 2009 semester. It’s a comprehensive assessment designed to evaluate understanding of fundamental data structure concepts and programming principles covered early in the course. The document includes the full exam questions as presented to students.
Why This Document Matters
This resource is exceptionally valuable for students currently enrolled in, or preparing to take, a similar data structures course. It provides a realistic glimpse into the exam format, question types, and difficulty level expected by instructors teaching this curriculum. Reviewing past exams is a proven strategy for identifying knowledge gaps, practicing problem-solving skills under timed conditions, and becoming familiar with the style of questions asked. It’s best utilized as part of a broader study plan, after initial coursework has been completed.
Topics Covered
