Walkthrough

Adds a new Go solution file that reads two integers from standard input using formatted scanf, sums them via an exported function, and prints the result with basic input error handling.

Changes

Cohort / File(s)	Summary
Challenge 1 Solution challenge-1/submissions/RP-Guruh/solution-template.go	New file: Go main package with fmt.Scanf input parsing for two comma-separated integers, Sum(a, b) exported function returning a + b, and error handling for malformed input.

7-19: The main function logic is correct.

The input reading, error handling, and result printing work as expected for the challenge requirements.

Optionally, consider using os.Exit(1) instead of return in the error handler to signal failure with a non-zero exit code:

 	_, err := fmt.Scanf("%d, %d", &a, &b)
 	if err != nil {
 		fmt.Println("Error reading input:", err)
-		return
+		os.Exit(1)
 	}

Don't forget to add the import:

 import (
 	"fmt"
+	"os"
 )

⚠️ Potential issue | 🟡 Minor

Remove the stale TODO comment.

The function is already implemented, but the TODO comment on Line 23 suggests otherwise. This can be confusing for future readers.

Apply this diff to remove the stale 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

	// Sum returns the sum of a and b.
	func Sum(a int, b int) int {
	// TODO: Implement the function
	return a + b
	}
	// 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/RP-Guruh/solution-template.go around lines 21 to 26,
remove the stale TODO comment on line 23 since the Sum function is implemented;
edit the function body to delete the "// TODO: Implement the function" line so
only the implemented code and necessary comments remain.
