# Daily LeetCode Solutions in Go ✏️
This repository contains my solutions to LeetCode problems in [Go](https://go.dev/).
## Folder Structure 🗂️
- `easy/`: Easy level problems.
- `medium/`: Medium level problems.
- `hard/`: Hard level problems.
## Unit Testing 🧪
In your root direction, run:
```bash
go test ./...
```
If you only want to run tests in a specific problem `(e.g., ./easy/0001_two_sum)`, run:
```bash
go test ./easy/0001_two_sum
```
Clean test cache
```bash
go clean -testcache
```

## Workflow 🌊
1. `go.yml`: This workflow runs whenver new code is pushed to main or create a pull request
- Runs all Go tests
- Checks code formatting with `go fmt`
- Runs `go vet` for static analysis
- Runs `staticcheck` for additional code quality checks
2. `update-stats.yml`: This runs whenever you push changes to your solution directory (`easy/medium/hard`). It:
- Counts the number of solutions in each level
- Update `README.md` with current stats
- Automaticall commits and pushes the changes
## Statistics 📊
- Easy: 8 solutions
- Medium: 17 solutions
- Hard: 2 solutions
- Total: 27 solutions
