Greedy strategy a. Does using the greedy algorithm for making change of n cents give a correct solution if a nickel was worth 6 cents instead of 5? (we have 1. 6. 10 and 25 cent coin denominations) b. We have n unique items. For i 12,3.n, each item has a weight w,> 0 and value v> 0. Write a greedy algorithm to find the maximum value of items that can be carried in a knapsack with a maximum weight capacity of W. An item may be broken into pieces and only a fraction put into the knapsack. It should take an aray of weights, an array of item values and the weight limit of the knapsack as input. The array of weights and items are ordered such that w, corresponds to the same item as v
