The Sliding Window technique is a powerful approach for solving problems involving subarrays or substrings by maintaining a "window" that slides over the data. This window can be of fixed size or variable size, depending on the problem constraints. I...
The Fast and Slow Pointer technique, also known as the "tortoise and hare" algorithm, uses two pointers moving at different speeds to solve problems involving linked lists or arrays, such as detecting cycles, finding midpoints, or checking palindrome...
Introduction The K-th Permutation Problem is a well-known problem in combinatorics where we need to find the k-th permutation of numbers from 1 to n. Instead of generating all permutations, we use a mathematical approach to find the k-th permutation ...
Trees are a fundamental data structure in computer science, and their traversal is a common operation in many algorithms. There are several ways to traverse a tree, each with its own advantages and disadvantages. One of the most straightforward and w...
Binary trees are a fundamental data structure in computer science, often used for searching and sorting algorithms. They are a tree-like data structure where each node can have at most two children, referred to as the left and right children. Here is...
Breadth-first search (BFS) and Depth-first search (DFS) are two popular algorithms used for traversing and searching in a graph. Both algorithms can be implemented using a generic class in Dart with null safety. Breadth First Search Graph Traversal A...
