Walkthrough

A Go program submission for Challenge 1 that reads two comma-separated integers from standard input, calls a Sum function to compute their sum, and prints the result. Includes an exported Sum function that returns the arithmetic sum of two integers.

Changes

Cohort / File(s)	Change Summary
Challenge 1 Go Solution challenge-1/submissions/AlexO-85/solution-template.go	Adds main function with stdin reading for two integers (formatted as "%d, %d"), error handling, and result printing; introduces exported Sum(a int, b int) int function that returns a + b

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~3 minutes

• Simple arithmetic operation with no edge case handling beyond standard input errors
• Straightforward I/O and function logic with no control-flow complexity
• Single file with minimal lines of code

Possibly related PRs

• PR #621: Adds nearly identical solution-template.go defining the same Sum function signature with matching Scanf input parsing for comma-separated integers
• PR #592: Adds challenge-1 solution file with identical Sum(a int, b int) int implementation and same "%d, %d" input/print pattern
• PR #559: Defines the same exported Sum function signature (a + b) with similar main I/O handling for Challenge 1

24-24: Consider removing the unnecessary semicolon.

While not an error, explicit semicolons are not idiomatic in Go, as the compiler automatically inserts them.

Apply this diff for more idiomatic Go:

-return a + b; +return a + b

The main function correctly reads two comma-separated integers from standard input, handles errors appropriately, and prints the sum.

⚠️ Potential issue | 🟡 Minor

Remove the misleading TODO comment.

The function is already implemented correctly. The TODO comment is misleading and should be removed.

Apply this diff to remove the TODO comment:

 // Sum returns the sum of a and b. func Sum(a int, b int) int { -// TODO: Implement the function	return a + b; }

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	// TODO: Implement the function
	// Sum returns the sum of a and b.
	func Sum(a int, b int) int {
	return a + b;
	}

🤖 Prompt for AI Agents

In challenge-1/submissions/AlexO-85/solution-template.go around line 23, remove the misleading "// TODO: Implement the function" comment because the function is already implemented; delete that single-line TODO comment (and run gofmt or save the file) so the source no longer contains the incorrect TODO.
