Python has become one of the most popular programming languages in the world, renowned for its simplicity, versatility, and vast ecosystem of libraries and frameworks. Alongside Python, there is PySpark, a powerful tool for big data processing that harnesses the distributed computing capabilities of Apache Spark. By combining the ease of Python with the scalability of Spark, developers can tackle large−scale data analysis and processing tasks efficiently. In this tutorial, we will explore the process of converting a list of dictionaries into a PySpark DataFrame, a fundamental data structure that enables efficient data manipulation and analysis in PySpark. In the ... Read More

In this problem, we need to take the maximum and minimum elements of all sub−array of length K and add them to get the answer. The first solution approach is that traverse through all sub−arrays of size K, find the minimum and maximum element of each sub−array, and add them. The optimized approach to solve the problem is using the deque data structure. We will store the index of the minimum and maximum elements of the subarray in the deque. Problem statement − We have given an array nums[] containing N positive or negative integer values. We have also ... Read More

In this problem, we will reduce the array size to 1 or 0 by performing the given operations in each turn. We can sort the array in each turn to get the maximum elements in each iteration. Also, we can use the head data structure to improve the performance of the code. Problem statement − We have given a nums[] array. We need to decrease the array by performing the below operations. Choose two maximum elements of the array. If both elements are the same, remove both elements from the array. If both elements are not the same, remove ... Read More

In this problem, we will perform the given queries on the array elements. The queries contain the circular left rotation, right rotation, and updation of the array element. The logical part of solving the problem is array rotation. The naïve approach to rotating the array in the left direction is to replace each element with the next element and the last element with the first element. We can use the deque data structure to rotate the array efficiently. Problem statement − We have given an arr[] array containing the integer values. Also, we have given a queries[] array containing ... Read More

Heap Sort − Heap sort is a comparison-based algorithm that used binary tree data structures to sort a list of numbers in increasing or decreasing order. It heap sorts to create a heap data structure where the root is the smallest element and then removes the root and again sorting gives the second smallest number in the list at the root position. Min Heap − Min heap is a data structure where the parent node is always smaller than the child node, thus root node is the smallest element among all. Problem Statement Given an array of integers. Sort them ... Read More
