To maximize learning, follow this 4-step protocol before consulting an answer key:
The most advanced step: create your own solution repository as you study. Format it in LaTeX or Markdown, upload to GitHub. You will:

## Exercise 3.2.4
**Problem:** (restate)
**Given:** ...
**Proof:** Step-by-step reasoning.
**Diagram:** (if needed)
**Verification:** Small example.
Problem: Prove that in a connected graph with ( n ) vertices and ( n-1 ) edges, the graph is a tree.
Typical Solution (From verified keys):
This logic, found in Deo’s solution sets, is the gold standard of rigor.
In many engineering circles, shared PDFs of “Deo solution manuals” circulate. Be careful: Many are incorrectly solved or contain typos in graph diagrams. Use them only for inspiration, not gospel. Graph Theory By Narsingh Deo Exercise Solution

For long-term learning (or if you’re an instructor), consider: To maximize learning, follow this 4-step protocol before
Because official resources are scarce, consider building your own annotated solution set. Here is a semester-long strategy:
