Question 13: Implement a function called charCombos from scratch that counts how many times each parameter z of letters occur sequentially in a string.

For example, charCombos('abcbcb', z=2)

should return ab:1, bc:2, cb: 2

charCombos('abcbcb', z=3) should return

abc: 1, bcb: 2, cbc: 1

Show that this function works with the string abcbcb and one other string of your choice.

Question 14: In the traditional English language, students are taught

"Always use a 'u' after a 'q'!". Using the function from question 13 (won't get full credit otherwise) and a link to a dictionary of English words provided below to determine the percentage of times that 'q' is indeed immediately followed by a 'u'.

Specifically, words containing q that are immediately followed by a u divided by total number of words containing q. Hint: Ensure you don't count q followed by whitespace.

Note for words with multiple q's or multiple q-u's, count them once.

Question 15: Find the top 5 most commonly used letters after q that are NOT equal to u sorted in descending order of frequency. For example, assume q_words includes all words containing the letter q. You can modify CharCombos to help with this.
