Recаll the greedy cаshier's аlgоrithm discussed in class fоr finding the minimum number оf coins to provide change for a specified amount. i) Prove that the cashier's algorithm does not always provide an optimal solution for the set of coin denominations: {1, 2, 7, 9, 16}. ii) Prove that the cashier's algorithm always provides an optimal solution for the set of coin denominations: {1, 2, 5, 15}. [Hint: Steps of the solution discussed in class are highlighted below to help you write your solution.] ii.a) Prove useful upper bounds for the number of coins occurring in any optimal solution. ii.b) Provide an inductive hypothesis to prove the claim inductively. ii.c) State a key claim regarding the greedy choice that would help complete the inductive step of your proof. ii.d) Prove the key claim by the constructing a table similar to the one constructed in class.
