Explain what are Spawn_link 1l3 and Spawn/ 1l3?
Spawn/ 1l3 creates a new process and return pid. In the system scheduler queue, the new process is created so that it runs later.
Spawn_link/1l3: provides the same functionality as spawn/1l3 but with an additional link that gets automatically created between the caller and the new spawn process.
