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 […]

What is a 2D Array? A 2D matrix is a two-dimensional array that contains rows and columns in data structures and methods. It is also known as a two-dimensional array. A matrix can be represented in code as a 2D array, where each element of the array is itself an array, and each row of […]

What is a SubArray? A subarray is a sequence of elements within an array that is contiguous. In other words, a subarray is a section of an array that contains consecutive elements in the same sequence as the original array. Subarrays can range in length from a single element (also considered a subarray) to the […]

What is Carry Forward? The word “carry forward” does not refer to a specific idea in data structures and algorithms. However, “carry forward” in the context of arrays often refers to the process of relocating entries in an array to fill in empty spaces left by deleted or removed elements. This is also referred to […]

What is Prefix Sum? Prefix Sum is a method for dealing with array manipulation challenges. It entails establishing an auxiliary array in which each element keeps the sum of all the components preceding it(including the current element). A prefix sum array is another name for this auxiliary array. Sample example to understand the concept: Explanation: […]

A group of related data elements stored at adjacent memory locations is referred to as an array. One of the most basic data structures, it allows for random access to each data element by its index number. Properties of an Array: Arrays contain a number of crucial characteristics that make them helpful in a wide […]

What is Time Complexity? Time complexity is a key concept in computer science, particularly in data structures and algorithms(DSA). It measures how long it takes to run an algorithm or complete a task, and it is usually expressed in terms of the input size. What Is Space Complexity? Space complexity is a measure of the […]

The Collection framework is found in java.util package includes Linked List. This class is an implementation of the LinkedList data structure, a linear data structure where each element is a separate object with a data part and address part and is not kept in a single location. Pointers and addresses are used to connect the […]
