What is Quick Sort? Quick sort is a common sorting algorithm that sorts an array using the divide-and-conquer technique. Quick sort works by selecting a pivot element, partitioning the array around the pivot element, and recursively sorting the sub-arrays. Algorithm: The basic steps of the Quick sort algorithm are as follows: Choose one of the […]

What is Insertion Sort? Insertion sort is a straightforward sorting algorithm that constructs the final sorted array one item at a time. It operates by splitting the input array into two parts: sorted and unsorted. The method then continually inserts the first unsorted element into the right location in the sorted section, moving the remaining […]

What is Selection Sort? Selection sort is a sorting method that finds the smallest element in an unsorted region of an array and places it at the beginning of the array. In the provided array, the method keeps two subarrays: The subarray that has previously been sorted The remaining unsorted subarray Algorithm: Algorithm for Selection […]

What is Bubble Sort? When neighboring components are arranged incorrectly, the straightforward comparison-based sorting algorithm known as Bubble Sort continuously swaps them. Its name refers to the way that items advance across the list while sorting, much like soda bubbles do in a glass. Algorithm: The algorithm works as follows: Starting from the first element, […]

What is Sorting in DSA? Sorting is a fundamental function in data structures and computer science. It is the process of organizing the contents of an array or list in a specific order in data structures and algorithms. There are various sorting algorithms that are regularly used in computer science, and the choice of method […]

What is Modular Arithmetic in DSA? Modular arithmetic is an arithmetic structure for integers, in which numbers “wrap around” when they reach a certain magnitude. Many areas of mathematics and computer science use modular arithmetic, including number theory, combinatorics, coding theory, and error-correcting codes. It is also utilized in algorithm design and analysis, notably in […]

In the previous topic, we got an introduction to Bit Manipulation in DSA. Let us now look at some examples using bit manipulation. Given two integers x and y, return the Hamming distance between them: Note: The Hamming distance between two integers is defined as the number of points where the corresponding bits differ. i.e, Input: x = 1, y = […]

What is Bits Manipulation? The process of modifying individual bits or groups of bits within a binary representation of data is known as bit manipulation. It is often used in computer programming to execute bit-level operations on data, which can be more efficient than typical arithmetic or logic operations. What is the need for bit […]

What is the Sliding Window Technique? The Window Sliding Technique is a technique for reducing the time complexity of algorithms using nested loops. We can avoid nested loops and obtain greater performance by traversing the array with a single loop and sliding a window over it. Use of Sliding Window Technique for 2D Arrays: A […]
