There are three main ways to check if a set is empty: Implicit: Pass the set into a Boolean context without modification. Python will automatically convert it to a Boolean using bool(). Explicit: Pass the set into the bool() Function. Comparison: Compare the set with the empty set like so: my_set == set() Let’s dive … Read more
Problem Formulation Given two arrays of the same length but different orders. How will you shuffle the two arrays in unison? Shuffling two arrays in unison means reordering the elements of both arrays in the same pattern. Let’s understand this with the help of an example. Example: Given:arr_1 = [[1, 1], [2, 2], [3, 3]]arr_2 … Read more
Use Python’s built-in max() function with the key argument to find the longest string in a set. Call max(my_set, key=len) to return the longest string in the set using the built-in len() function to determine the weight of each string—the longest string has maximum length. 👉 Recommended Tutorial: How to Find the Longest String in … Read more
