The primary operations associated with this data structure are: * Find: Determine which subset an element belongs to. This is typically used to check if two elements are in the same subset. * Union: Join two subsets together, combining them into a single subset. The disjoint-...")

• 22:32, 6 May 2023 Admin talk contribs created page Flood Fill (Created page with "Flood fill is a simple algorithm used to explore and fill connected regions in a 2D grid or matrix. It is often used in image processing to fill areas with a specified color, but it can also be used in solving graph problems such as finding connected components or traversing a maze. The algorithm starts from a given cell (row, col) and recursively explores its neighbors (usually up, down, left, and right) to fill the region with a new value or to mark it as visited. The...")

• 04:59, 6 May 2023 Admin talk contribs created page Binary Search (Created page with "== Binary Search == Binary Search is an efficient algorithm for finding a specific element (target) in a sorted array or list. The algorithm works by repeatedly dividing the search interval in half. At each step, the algorithm compares the middle element of the interval with the target value. If the middle element is equal to the target, the search is successful. If the target is less than the middle element, the search continues in the left half of the interval. If the...")

DFS can be implemented using recursion or an explicit stack data structure. === Algorithm === Start at the source node and mark it as visited. For each adjacent node of the source node, if it is not visited, perform a recursive DFS from the adjacent node. === Time Complexity ===...")

It starts at the tree’s root or graph and searches/visits all nodes at the current depth level before moving on to the nodes at the next depth level. <ref name=“geeksforgeeks”>https://www.geeksforgeeks.org/breadth-first-search-or-bfs-for-a-graph/</ref> == How it works == BFS uses a queue data structure to...")
