Q7 a. What would be a good hash code function for a vehicle identification number, that is a string of numbers and letters of the form "9X9XX99X999", where '9' represents a digit and 'X' represents a letter? [1]

Q7 b. Given a hash table of size 13, show the contents of your hash table after inserting the values {8, 2, 7, 18, 15, 19, 23, 15, 20, 16} using open addressing with quadratic probing ( f(i) = i2 ) for collision resolution. Repeat the question using separate chaining for collision resolution.
