CS-260 Data Structures and Algorithms shares its title and core subject matter with CS-218 — covering stacks, queues, trees, graphs, hash tables, and sorting algorithm analysis — representing a parallel catalog listing rather than a distinct course. SNHU's catalog also lists a related CS-300 under a similar name, following the same parallel-numbering pattern seen elsewhere in the university's course structure.
A parallel listing, not distinct content
The course's identical title and overlapping subject matter with CS-218 (and a third listing, CS-300) reflect SNHU's broader pattern of maintaining parallel course numbers for the same underlying content, likely to serve different programs or delivery formats.
What CS-260 actually covers
Like CS-218, CS-260 covers fundamental data structures — stacks, queues, trees, graphs, hash tables — and rigorous sorting algorithm analysis, building the same practical implementation competency.
Key topics in CS260
- Fundamental data structures (shared with CS-218)
- Sorting algorithm analysis
- Implementing core data structures
- Time and memory complexity
- Recognizing parallel course numbering in the SNHU catalog
- Algorithm design fundamentals

Our writers help with CS-260 data structures and algorithms assignments — the same guidance applies as for CS-218.
Worked example: recognizing a three-way parallel listing
- Signal: CS-218, CS-260, and CS-300 all appear in SNHU's catalog under variations of "Data Structures and Algorithms"
- Interpretation: Rather than three distinct courses, this is one subject appearing under multiple catalog numbers across different programs or catalog eras
- Lesson: Recognizing this pattern (also seen in Accounting, Marketing, and Chemistry) helps students correctly identify which number applies to their specific program

Frequently asked questions
Universities often maintain parallel course numbers for identical or near-identical content to serve different degree programs, campus-versus-online delivery, or different points in the catalog's revision history, without needing to redesign the underlying course material each time. This pattern shows up repeatedly across SNHU's catalog (also seen in Accounting, Taxation, Marketing, and Chemistry courses), and for a student, the practical material — data structures, algorithm analysis, implementation — is the same regardless of which specific number their program lists.
For the core learning content, no — both courses cover the same fundamental data structures and sorting algorithm analysis — but the specific number matters for satisfying a particular program's degree requirements, since a degree plan may reference one specific number rather than the other. Students should confirm with their academic advisor which number their specific program requires, even though the underlying coursework is equivalent.
