WebA Greedy algorithm makes greedy choices at each step to ensure that the objective function is optimized. The Greedy algorithm has only one shot to compute the optimal solution so that it never goes back and reverses the decision. Greedy algorithms have some advantages and disadvantages: WebCounting Coins. 1 − Select one ₹ 10 coin, the remaining count is 8. 2 − Then select one ₹ 5 coin, the remaining count is 3. 3 − Then select one ₹ 2 coin, the remaining …
