Given a list of countries, each on a new line, your task is to read them into an array and then display the count of elements in that array.
Here's a great tutorial tutorial with useful examples related to arrays in Bash.
A list of country names.
The only characters present in the country names will be upper or lower case characters and hyphens.
A single integer - the number of elements in the array.
There are 10 elements in the array - i.e. the given list has the names of 10 countries.
