go run .

or

go run main.go

2. Production environment executable file (Linux env)
   a) While in the project root directory
   b) Run command below

A binary executable file will be created in directory path bin/
To execute the binary file in the created bin directory

1. reload -> Application to fetch and update the list of currency codes while already running
2. exit -> application exiting gracefully
3. help -> displays instructions for using the application
4. Application accepts multi input currency code search as long the codes are comma separated
