Let a be the number from your NetID (for example, if your NetID is xy72, your number is a = 72). You are not allowed to pick any other number. Let n = 2000 + a and m = 10000 a. Consider the Karatsuba multiplication algorithm with base case n = 1 instead of n = 64 and all operations with digits performed base 10 instead of base 2. Draw the tree of all the recursive calls made by such an algorithm for multiplication n by m.
