Скачать или смотреть Find the TWO keys with the highest values in a dictionary | Python

Description: In this video, we're tackling the challenge of finding the two keys with the highest values in a Python dictionary. We will compare two different algorithms and break down their time complexity.

Algorithm 1 - Sorting Approach:
We kick things off by introducing Algorithm 1 - the Sorting Approach. This version involves sorting the dictionary items by their values in descending order and then selecting the first two items using in-built methods. However, we'll quickly uncover the limitations of this method and why it doesn't work as expected for dictionaries.

Algorithm 2 - Linear Scan Method:
Next, we dive into Algorithm 2 - the Linear Scan Method. This algorithm takes a more efficient approach by scanning through the dictionary just once. We'll guide you through the step-by-step process of how this algorithm identifies the two maximum value entries and discuss its impressive time complexity of O(N) and minimal space complexity of O(1).

By the end of this video, you'll have a solid grasp of both the Sorting Approach and the Linear Scan Method for finding the two keys with the highest values in a dictionary. Stay tuned for algorithm insights, coding tips, and a better understanding of time complexity nuances.
