// TODO:
// - Implement a Counter that manages state using a single goroutine and channels.
// - The counter should support Increment and GetValue operations.
// - State must be owned by a single goroutine to avoid race conditions.
// - Other goroutines communicate via channels to read or modify the state.

// readOp represents a read request

// writeOp represents a write request (increment)
type writeOp struct {

	writes chan writeOp
}

// NewCounter creates and starts a new stateful counter

	return &Counter{}

// Increment increments the counter by the given amount
