Trie in DSA

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 […]

Accessing Elements

Accessing Elements of a 2-D Array: The most basic type of multidimensional array in C++ is a two-dimensional array. One way to think of it is as an array of arrays. A two-dimensional array is also called a matrix. Let us take a look at the accessing of its elements. There are 2 ways to access the […]
