Algorithms & DSA

A DSA assignment is rarely graded on the answer alone — you're expected to explain why it's O(n log n) and not O(n²), and defend that on the spot. We deliver the implementation with the complexity analysis written out and walk through the trace with you first, so the explanation is yours to give, not ours to have given you.

What you get

• Implementation plus a Big-O breakdown for time and space
• Test cases covering the edge cases markers actually probe
• Trees, graphs, heaps and hash structures built from first principles
• Trace-through explanations you can reproduce on a whiteboard
• Optimised only where the brief asks for it, not over-engineered
• A walkthrough call before any viva or code defence

What to send first

• The assignment PDF and the marking rubric
• Any starter code, skeleton files or header files you were given
• The exact language version and compiler or IDE your marker uses
• Sample inputs, expected outputs or the autograder's test cases

How it runs

1. 01

   Send the spec

   The brief, the rubric, any starter code and the versions your marker uses. A photo of the PDF is fine to begin with.

2. 02

   Scope and quote in writing

   We read it properly, ask what is unclear, and confirm a fixed price and delivery date. A small advance confirms the order.

3. 03

   Build against the brief

   Work is tracked task by task against the spec. Longer projects are split into milestones you can review as they land.

4. 04

   Tested handover

   A repo that installs from a README, run against your test cases, with the write-up if your rubric asks for one.

5. 05

   Fixes and walkthrough

   One round of fixes if a marker flags something, and a walkthrough of how it works so you can explain it.
