Walkthrough

Adds a new Go program file implementing a simple CLI workflow for Challenge 1. The program reads two integers from standard input, computes their sum via an exported function, handles input parsing errors, and outputs the result.

Changes

Cohort / File(s)	Change Summary
New Challenge 1 Solution challenge-1/submissions/lostzoo/solution-template.go	Adds new Go file with exported Sum(a int, b int) int function, main entry point that reads two comma-separated integers via fmt.Scanf, error handling for input parsing, and printed output of the sum.

11-14: Consider improving error handling to follow Go best practices.

The current error handling prints to stdout and returns without exiting with a non-zero status code. For better CLI behavior, errors should be written to stderr and the program should exit with a non-zero code.

Apply this diff to improve error handling:

+import ( +"fmt" +"log" +) + func main() {	var a, b int	// Read two integers from standard input	_, err := fmt.Scanf("%d, %d", &a, &b)	if err != nil { -fmt.Println("Error reading input:", err) -return +log.Fatal("Error reading input:", err)	}

Alternatively, you can use os.Exit(1) if you prefer not to use the log package.

21-25: Consider simplifying the Sum function.

The intermediate variable result is unnecessary for such a simple operation. While the current implementation is correct, it can be more concise.

Apply this diff to simplify:

 // Sum returns the sum of a and b. func Sum(a int, b int) int { -result := a + b -return result +return a + b }

⚠️ Potential issue | 🔴 Critical

Fix indentation: use tabs instead of spaces.

Line 23 uses spaces for indentation instead of tabs, which violates Go's formatting standards. Run go fmt on this file to automatically fix the indentation.

The line should use a tab character for indentation to comply with gofmt:

 func Sum(a int, b int) int { - result := a + b +result := a + b	return result }

🤖 Prompt for AI Agents

In challenge-1/submissions/lostzoo/solution-template.go around line 23, the statement is indented with spaces (" result := a + b") instead of a tab; run `gofmt -w challenge-1/submissions/lostzoo/solution-template.go` (or replace the leading spaces with a single tab) to correct the indentation so the file conforms to Go formatting.
