Get started for freeTrace Algorithm 4 when it is given m = 7 , n = 10 , and b = 2 as input. That is, show all the steps Algorithm 4 uses to findmod 7 .
Trace Algorithm 3 when it finds gcd (8,13). That is, show all the steps used by Algorithm 3 to find (8,13).
Prove that the recursive algorithm that you found in Exercise 10 is correct.
Suppose you begin with a pile of n stones and split this pile into n piles of one stone each by successively splitting a pile of stones into two smaller piles. Each time you split a pile of stones into two smaller piles. Each time you split a pile you multiply the number of stones in each of the two smaller piles you form, so that if piles haver and s stones in them, respectively, you compute rs. Show that no matter how you split the piles, the sum of the products computed at each step equals .
Prove that the first player has a winning strategy for the game of Chomp, introduced in Example 12 in Section 1.8, if the initial board is square. [Hint: Use strong induction to show that this strategy works. For the first move, the first player chomps all cookies except those in the left and top edges. On subsequent moves, after the second player has chomped cookies on either the top or left edge, the first player chomps cookies in the same relative positions in the left or top edge, respectively.]
