💡 Problem Formulation: Determining the perimeter of a polygon is a fundamental geometric problem, which involves calculating the sum length of all the sides of the polygon. For instance, given the coordinates of a pentagon’s vertices, the goal is to compute the total distance around its five edges. This article explores various Python methods to … Read more

💡 Problem Formulation: Complex numbers, used extensively in engineering and science, consist of a real part and an imaginary part. For example, 3 + 4i is a complex number with the real part being 3 and the imaginary part 4i. This article explores how to create a Python class that can handle complex numbers, allowing … Read more

💡 Problem Formulation: Prefix compression involves reducing two input strings to their common beginning, followed by the two unique remainders. Given strings ‘string1’ and ‘string2’, the goal is to identify the common prefix and output a tuple: (length_of_common_prefix, unique_part_of_string1, unique_part_of_string2). For example, for ‘interspecies’ and ‘interstellar’, the desired output would be (5, ‘species’, ‘stellar’). Method … Read more

💡 Problem Formulation: String compression is a common programming challenge where the goal is to reduce the size of a string by replacing consecutive repeats of characters with the character followed by the count of repeats. For instance, the input ‘aabcccccaaa’ should yield an output of ‘a2b1c5a3’. Method 1: Using Loops This method involves iterating … Read more

💡 Problem Formulation: The task is to create a Python program that can swap characters in a string pairwise. For example, given the input string “example”, the program should output “xemalpe”. Swapping pairwise means that each pair of adjacent characters is exchanged, which is a common task in string manipulation and coding challenges. Method 1: … 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
