Groundswell Technical Challenge

Description

The page should allow up to ten letters of the alphabet to be entered into a text input field. It also has a display button, named Calculate, which when clicked will perform the following functionality:

• Translate each alphabetic character entered as follows – a=1, b=2, c=3, and so on to z=26
• Add the numeric values of each translated character together and display the result on the page
• Check whether the result is a prime number or not and display some text saying which it is

Example 1: Input: aaa Output: 3 is a prime number

Example 2: Input: abc Output: 6 is not a prime number

Example 3: Input: azb Output: 29 is a prime number

Technical Notes
