How To Calculate Time Complexity With Big O Notation

WebSep 6, 2024 · The big-O time is O(n) (for every node in the tree). However, the space complexity for these algorithms varies. For BFS, which traverses all nodes at a given depth in the tree and uses a queue implementation, the width of the tree matters. The space complexity for BFS is O(w) where w is the maximum width of the tree. WebSpace complexity denotes the memory space with respect to input size used up by the algorithm until it is executed fully. To execute Prim's algorithm, we need an array to maintain the min heap. It takes up space E, where E is the number of edges present. We also need an array to store the vertices visited. philips ingenia mri
