Describe how you would use sub-benchmarks in Go.
- Sub-benchmarks are not supported in Go.
- Define multiple benchmark functions in the same file.
- Use the b.Run method within a benchmark function.
- Group benchmarks in separate test files.
In Go, sub-benchmarks can be created using the b.Run method within a benchmark function. This allows you to create multiple benchmarks within a single benchmark function, each with its own name and b.N value. Sub-benchmarks are useful for testing different scenarios or variations of a function or code. They provide a convenient way to organize and run benchmarks for different cases within the same benchmark function.
