Implement a stack using the given structure.

Concurrency is the ability to run multiple tasks simultaneously, achieving parallelism.

• Go uses goroutines to achieve concurrency

• Goroutines are lightweight threads managed by the Go runtime

• Concurrency in Go is achieved using channels for communication between goroutines

Types of channels in Go and their use cases

• Buffered channels: Allow multiple senders to send data without blocking until the buffer is full

• Unbuffered channels: Synchronize goroutines by blocking sender until receiver is ready

• Bidirectional channels: Allow both sending and receiving data

• Receive-only channels: Restrict channel to only receive data

• Send-only channels: Restrict channel to only send data
