Flood fill algorithm time complexity. You are given an image represented by an m x n grid of integers, where the image[i] represents the pixel value at position (i, j). There are many ways to optimize and extend the basic algorithm. Dec 1, 2025 · Search and rescue teams working in post-earthquake areas often face unstable debris and shifting structures that make navigation unpredictable, while most pathfinding algorithms, such as A*, Dijkstra, and the classical Flood Fill, assume a static environment and struggle once walls move or multiple agents explore the same space. We also included C++ and Python programs for flood fill. Jun 4, 2023 · Overall, the time and space complexity of the flood fill algorithm are both linear, depending on the size of the connected region. Space Complexity: O (n) is the worst case space complexity for recursive implementations due to the use of stack data structures. Aug 28, 2023 · Regarding time complexity estimation, the algorithm’s performance is influenced by the total number of pixels in the image and the size of the region designated for filling. Detailed tutorial on Flood-fill Algorithm to improve your understanding of Algorithms. To save computation time, the modified flood fill algorithm is often coded. Choice of Data Structure: Recursive implementation uses a stack data structure, while iterative Jul 28, 2013 · Is the flood fill algorithm the same as depth first search? If not, how do they differ in complexity? Mar 27, 2024 · The flood fill algorithm helps in the visitation of all points within a specified area. hhcgditlzvemkmbmbvhzdqtbtjelepasvtnmpekcrimr
