The challenge in this algorithm is when given a string, return the frequency of each letter in the string, in addition, ignore any spaces, special characters or numbers …

Another simple string algorithm. In this one, the challenge is to return the provided string with the first letter of each word capitalized. Make sure the rest of the word is in lower case.

In this algorithm we will see how to take a number, then find its factorial. If you forgot from your math class what a factorial is it is just the product of an integer and all the integers below. For example, the factorial of 5 would be: 5! = 1 * 2 * 3 * 4 * 5 = 120.

I decided to start practicing algorithm to improve my problem-solving skills. I figured it would be fun to start posting them here on the site for others that might be interested.
