Introduction Statisticians skillfully mesh probability distributions with relevant data sources, thereby lending (or disavowing) plausibility to wide-ranging, though pertinent, hypotheses regarding variable complexities within those databases. In this realm, the Tukey Lambada distribution distinguishes itself via distinct features. With its versatility, the Tukey distribution efficiently models diverse datasets showcasing varied shapes, tails, and degrees of asymmetry. As we dive into Python implementation, it's crucial to understand the Tukey-Lambda distribution's fundamental traits first. Understanding the Tukey-Lambda Distribution In 1960s, John W. Tukey developed the Tukey-Lambda distribution – a statistical constant probability distribution. Flexible enough to accommodate multiple shape variances, this distribution ... Read More

List in python allows duplicate entries, that is we can have the same value twice in a list. That is useful in most cases, but sometimes there is a need to remove the duplicate elements to perform certain operations. In this article we will focus on how we can take up the unique values removing duplicates from a list of integers and finding their product. It has a wide use case scenario and we will try and discuss all possible ways to generate the output. Method 1: Set Implementation Set in python is unordered data collection that is iterable, mutable ... Read More

In this article, we will have input as a list of tuples and our goal will be to print the frequency of unique tuples but it will be order irrespective. Order irrespective means that a tuple (1, 2, 3) and (1, 3, 2) will be treated as same even though their order is different. For example, consider the following − Input [(1, 2, 3), (2, 1, 3), (4, 5, 6), (1, 2, 3), (3, 2, 1)] Output 2 Explanation The tuples at index 0, 1, 3 and 4 are same and hence frequency count increases by ...

In Python, when dealing with matrices of uneven row lengths, the efficiency in locating each column's minimum values becomes paramount; a variety of approaches each boasting its own strengths and suitability for different scenarios exist to tackle this task. We are going to delve into several methods within this article: from basic nested loops all the way up to advanced tools such as NumPy and Pandas. Ultimately, you will grasp a comprehensive understanding of two crucial skills: mastering the manipulation of uneven-sized matrices and extracting valuable information from them. Method 1: Using Nested Loops This method, utilizing nested loops, iterates ... Read More

Dictionaries in python are widely used, to store data in key-value pairs. Many times, we get stuck in finding the product of elements in the tuple received as value in the dictionary. This mostly arises in situations working with data manipulation or analysis. Through this article, we will code and understand various ways to unpack the dictionary and calculate the product of tuple elements at each index. Input {'a': (1, 3, 5, 7), 'b': (2, 4, 6, 8), 'c': (2, 3, 5, 7)} Output (4, 36, 150, 392) Method 1: Using Tuple Unpacking and zip() Function ... Read More

Python tuples store data in the form of individual elements. The order of these elements is fixed i.e (1, 2, 3) will remain in the same order of 1, 2, 3 always. In this article, we are going to see how to invert python tuple elements or in simple terms how to reverse the order of the elements. Let us 1st see a sample input and output − Input (5, 6, 7, 8) Output (8, 7, 6, 5) Let us now explore the various ways to invert tuple elements. Method 1: Using Tuple Slicing Slicing is ... Read More

Given 2 separate lists, we are going to transform them into a single data structure by mapping them into a key-value data structure namely dictionary. The values of the 1st list will serve as keys and values from the 2nd list will serve as values of the corresponding keys in the dictionary. The relationship can be considered as 1 to 1 or 1 to many i.e. 1 key can have multiple values. Let us now see a sample input and output to better understand how we will be able convert Lists into Similar key value lists in Python in this ... Read More

In this article, we will do a three-way partitioning of an array containing N integers. The approach is to use three queues. Each of these queues will be used to store the elements of one of the parts. After that, we can get the elements of each part from their respective queues without changing the relative order of the elements Problem Statement Given an array containing N integers and a range [LOW, HIGH], we need to partition the array into three parts such that − Elements less than LOW comes first Elements greater than LOW and lower than HIGH ...

In this article, we will calculate the sum of the array maximums after K operations in which we reduce the maximum value of the array to its half. In the first approach, we will implement the brute force solution to this problem. In each iteration, we will use a for loop to find the maximum element in the array. We will then add this element to our answer, then we will reduce the element to its half. We will do this for K iterations as requested. Then, we will return the answer. In the second approach, we will use a ... Read More

In this article, we will sort the given array. The given array is already sorted on the basis of absolute value of the elements, we just need to sort the array based on the true values of the elements. In the first approach, we will use a sorting algorithm, like merge sort, bubble sort, insertion sort, quicksort and so on. In this example, we will use the inbuilt sort function to sort our array. In the second approach, we will use a double ended queue. We will push the positive elements in front of the double ended queue, and we ... Read More
