💡 Problem Formulation: You have a collection of elements and multiple sets. The goal is to determine the ‘happiness’ of the collection based on the presence of its elements in two specific sets: a ‘happy’ set and a ‘sad’ set. For each element in the collection that is in the happy set, happiness increases by … Read more

💡 Problem Formulation: The task is to find the angle at the base of a right-angled triangle, using the midpoint of the hypotenuse as one vertex and the ends of the base as the other vertices. The input would typically be the lengths of the sides of the triangle, and the output is the angle … Read more

💡 Problem Formulation: Given a string, the challenge is to divide it into k distinct partitions such that each partition is as even as possible. For instance, if the input string is “aabbccdd” and k = 4, the desired output would be [“aa”, “bb”, “cc”, “dd”]. This article explores various methods to achieve this partitioning … Read more

💡 Problem Formulation: In the Minion game, two players create words from a given string. The player with the most points wins. A vowel opening a word scores points equal to the remaining length of the string. The task is to write a Python program that computes the scores and declares the name of the … Read more

💡 Problem Formulation: In Python, you may often need to manipulate list items. A common task is updating a list so that each element becomes the absolute value of the original element. For instance, given the input list [1, -4, 3, -2], the desired output would be [1, 4, 3, 2]. This article explores five … Read more

💡 Problem Formulation: Finding a better or ‘best’ divisor of a number means finding a divisor which is neither too high nor too low in its value. In an ideal situation, we strive to find divisors that are close to the square root of a number to avoid pairing small with large divisors. For instance, … Read more

💡 Problem Formulation: Python developers typically use the built-in len() function to find the length of a list. However, understanding alternative methods can improve one’s grasp of Python’s iterators and loops. This article aims to elucidate how to find the length of a given list, such as my_list = [1, 2, 3, 4], where the … Read more

💡 Problem Formulation: Given a list of numbers in Python, the task is to calculate the sum of all the odd numbers contained within it. For example, if the input is [1, 2, 3, 4, 5], the expected output is 9, since 1 + 3 + 5 = 9. Method 1: Using for-loop and Modulus … Read more

How to Reverse a List with List Slicing in Python 💡 Problem Formulation: How can a list in Python be reversed in place without using built-in functions? Given an input list [1, 2, 3, 4, 5], the desired output is a list in reversed order: [5, 4, 3, 2, 1]. This article demonstrates five ways … Read more

💡 Problem Formulation: When programming in Python, you may encounter scenarios where you need to generate a sequence of numbers from 1 to n as a list. This task forms the basis of many algorithms and is handy for generating test data, iterating over loops, numerical computations, and more. For example, if the input is … Read more

💡 Problem Formulation: You have a collection of height measurements but they include duplicate entries for individuals. Our goal is to compute the average height per individual, then, using only the distinct data points, to calculate the overall average height. Imagine input as a list of tuples ((‘Name’, Height_in_cm)), and the desired output is a … Read more

💡 Problem Formulation: Python developers often need to retrieve elements from a list based on their indexes. Specifically, you may need a way to extract only the items that are positioned at even indexes within a list. For instance, given the input list [3, 7, 2, 8, 5, 10], the desired output would be [3, … Read more
