Parallel Letter Frequency

Instructions

Count the frequency of letters in texts using parallel computation.

Parallelism is about doing things in parallel that can also be done sequentially. A common example is counting the frequency of letters. Create a function that returns the total frequency of each letter in a list of texts and that employs parallelism.

For this exercise the following F# feature comes in handy:

• Asynchronous programming .NET has asynchronous functionality built-in which enables you to run things in parallel (assuming you have a multi-core processor which is becoming more an more common) easily
