Walkthrough

Added a new Go solution file containing a ReverseString function that converts a string to runes, reverses the slice in-place, and returns the result. The main function reads a single line from standard input, processes it through ReverseString, and outputs the reversed string.

Changes

Cohort / File(s)	Summary
Challenge 2 Submission challenge-2/submissions/ansmonjol/solution-template.go	New file added with ReverseString(s string) string function that reverses strings by converting to runes and swapping in-place, plus a main function that reads stdin, reverses the input, and prints the result

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Straightforward string reversal implementation with no complex logic

9-21: Consider checking for scanner errors.

The code reads input but doesn't check if scanner.Scan() returned false due to an error versus EOF. Consider checking scanner.Err() after the scan to distinguish between these cases and provide better error handling.

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)
+	}
 }

23-36: LGTM! Excellent implementation.

The ReverseString function correctly handles Unicode characters by converting to runes and uses an efficient two-pointer approach for in-place reversal. The logic properly handles edge cases like empty strings and single characters.
