Walkthrough

Adds two new Go solution files: one reads two comma-separated integers, calls Sum(a int, b int) int, and prints the sum; the other reads a line, calls ReverseString(s string) string, and prints the reversed string.

Changes

Cohort / File(s)	Summary
Challenge 1 Solution challenge-1/submissions/Maidomax/solution-template.go	New file: CLI program that reads two comma-separated integers from stdin, calls Sum(a int, b int) int, and prints the result. Sum returns a + b.
Challenge 2 Solution challenge-2/submissions/Maidomax/solution-template.go	New file: CLI program that reads a line from stdin, calls ReverseString(s string) string which reverses rune-wise, and prints the reversed string.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Two small, self-contained files with straightforward logic.
• Check parsing edge-cases and rune handling in ReverseString.
• Validate error handling and input trimming in both mains.

• Add solution for Challenge 2 by ymonn #739: Adds both Sum(a int, b int) and ReverseString(s string) implementations in challenge submissions (directly related to both functions).
• Add solution for Challenge 1 by redstrike #595: Adds the same Sum(a int, b int) int function and similar main CLI logic for challenge-1 (same symbol/path domain).

Pre-merge checks

❌ Failed checks (2 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'First challenge solved' is vague and generic; it does not clearly describe which challenges were solved or what specific changes were made to the codebase.	Update the title to be more specific about the changes, such as 'Add Go solutions for challenge-1 and challenge-2' or 'Implement Sum and ReverseString functions'.
Description check	❓ Inconclusive	No pull request description was provided by the author, making it impossible to assess whether the description relates to the changeset.	Add a description explaining the changes made, such as which challenges were solved and what functions were implemented.

7-19: LGTM!

The main function correctly reads two integers from standard input, handles read errors appropriately, and prints the result of the Sum function.

⚠️ Potential issue | 🟡 Minor

Remove the outdated TODO comment.

The function is already implemented on line 24. The TODO comment is misleading and should be removed to avoid confusion.

Apply this diff to remove the TODO comment:

 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
	func Sum(a int, b int) int {
	return a + b
	}

🤖 Prompt for AI Agents

In challenge-1/submissions/Maidomax/solution-template.go around line 23, remove
the outdated "// TODO: Implement the function" comment because the function is
already implemented on the following line; simply delete that single-line
comment so the code no longer contains a misleading TODO.

9-21: Consider adding error handling for scanner errors.

The main function logic is clean and correct. However, bufio.Scanner can encounter errors during reading that should be checked with scanner.Err() after the scan loop completes.

Apply this diff to add error handling:

 func main() {
 	// Read input from standard input
 	scanner := bufio.NewScanner(os.Stdin)
 	if scanner.Scan() {
 		input := scanner.Text()
 
 		// Call the ReverseString function
 		output := ReverseString(input)
 
 		// Print the result
 		fmt.Println(output)
 	}
+	if err := scanner.Err(); err != nil {
+		fmt.Fprintf(os.Stderr, "Error reading input: %v\n", err)
+		os.Exit(1)
+	}
 }

23-33: LGTM!

The ReverseString implementation is correct and handles Unicode properly by converting to runes before reversing. The two-pointer swap technique efficiently reverses the string in-place.
