A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time. WebAug 4, 2024 · 2. Running time. Running time is the main factor to classify sorting algorithms. In a coding interview, when asked about the time complexity of your algorithm, the interviewer is usually looking for worst-case time complexity. In practice, however, the average case and the performance of the algorithm on all sets of data is what’s mostly ...
