Solution
- Breadth-first search (BFS) and Depth First Search (DFS) is an algorithm for traversing or searching tree or graph data structures.
- Breadth First Search (BFS) algorithm traverses a graph in a breadthwise manner and uses a queue to remember to get the next vertex to start a search, when a dead end occurs in any iteration.
- Depth First Search (DFS) uses Stack data structure. DFS uses backtracking technique. Remember backtracking can proceed by Stack.
- Heapsort is a comparison-based sorting algorithm.
