Goroutines are created using the 'go' keyword in Go programming language.
They are more lightweight than threads and are managed by the Go runtime.
Goroutines allow for concurrent execution of functions without the need for manual thread management.
Example: go myFunction()
Example: go func() { // code here }

- Q2. What is a regular language?
- Ans.
A regular language is a language that can be recognized by a finite automaton.
Regular languages can be described by regular expressions.
Regular languages are closed under union, concatenation, and Kleene star operations.

- Q3. What are NP and NP-Hard problems?
- Ans.
NP problems are decision problems that can be verified in polynomial time, while NP-Hard problems are at least as hard as the hardest problems in NP.
NP problems can be verified in polynomial time but not necessarily solved in polynomial time.
NP-Hard problems are at least as hard as the hardest problems in NP, but may not be in NP themselves.
