How can you use the context package in Go to manage cancellation and timeouts in a concurrent environment?

In Go, the `context` package provides a powerful mechanism for managing cancellation and timeouts in a concurrent environment. It allows you to propagate signals and deadlines across goroutines and provides a way to gracefully cancel or timeout operations when needed. The `context` package introduces the `Context` type, which represents the context of an operation. A `Context` can be created using the `context.Background()` function, which returns a background context that serves as the root of the context tree. You can then create derived contexts using the `context.WithCancel()` or `context.WithTimeout()` functions. 1. Cancellation: To manage cancellation, you can create a context with cancellation capability using the `context.WithCancel()` function. This function returns a new derived context and a corresponding `cancel` function. When the `cancel` function is called, it signals that the operation associated with the context should be canceled.
