Write a stored procedure named displayCountryMessage(). The displayCountryMessage () should receive one input argument for the country name and then based on that input argument, display a short message and the name of the country. Otherwise, if the country does not exist in the country table, then the procedure should display an appropriate message.

Please use javascript to write the function. write the code for the edit() function. This function prompts the user for a unique code. If the entered unique code is matched with the random-generated unique code for the respective user, store the user index and reason index to the local storage with their relevant key. Then redirect the user to the edit page. Otherwise, if the unique code cannot match with the user’s random-generated unique code, alert the user by mentioning that incorrect unique code.
