Code Review for PR #116

I've reviewed the LeetCode 165 (Compare Version Numbers) solution and have several suggestions for improvement.

Todo List:

• Read repository guidelines (CLAUDE.md) - No repo guidelines found
• Read and analyze solution/165/main.go
• Provide comprehensive code review feedback
• Suggest improvements

Review Feedback

Issues Found:

1. Missing Import Statement ⚠️
The code uses strings.Split() and strconv.Atoi() but lacks the required imports:

// Missing at top of file:
import (
    "strconv"
    "strings"
)

This will cause compilation errors.

2. Error Handling ⚠️
Line 13 & 16: strconv.Atoi() errors are ignored with _. While version strings typically contain valid integers, proper error handling would be more robust:

val, err := strconv.Atoi(rev1[i])
if err != nil {
    // Handle invalid version format
}

3. Code Style Issues 🔧

• Line 7 & 18: Commented-out debug statements should be removed in production code
• Inconsistent spacing around comments and code blocks
• Variable names could be more descriptive (rev1/rev2 → parts1/parts2)

Potential Improvements:

1. Memory Optimization 💡
Instead of creating two separate integer slices, you could compare parts on-demand:

func compareVersion(version1, version2 string) int {
    parts1 := strings.Split(version1, ".")
    parts2 := strings.Split(version2, ".")
    
    maxLen := max(len(parts1), len(parts2))
    
    for i := 0; i < maxLen; i++ {
        v1 := getVersionPart(parts1, i)
        v2 := getVersionPart(parts2, i)
        
        if v1 < v2 {
            return -1
        } else if v1 > v2 {
            return 1
        }
    }
    return 0
}

2. Algorithm Logic ✅
The core algorithm is correct and handles the key cases:

• Comparing corresponding version parts
• Handling different length version strings by checking remaining parts for non-zero values
• Proper return values (-1, 0, 1)

Minor Suggestions:

• Add a package comment explaining the problem being solved
• Consider adding a main() function with test cases
• Use more descriptive variable names for better readability

Overall Assessment:

The solution correctly implements the version comparison logic, but needs import statements to compile and could benefit from better error handling and code cleanup.
