BFS and DFS are just ways to iterate over a graph, there are many problems that both of them does the job. You can think of BFS like slowly iterating over all neighbours (iterates over all with distance 1, then all with distance 2, then all of distance 3...) and DFS just going ...

Nothing stops to traverse search space tree using BFS and execute backtracking strategy along the way, but it doesn't make sense in practice because you would need to store search state layer by layer in the queue, and tree width grows exponentially to the height, so we would waste a l...

For example, it probably does not make much sense to use A*, or its non-heuristic counterpart “Dijkstra's algorithm”, on a tree (where there is only one path to choose anyway, which you can find by DFS or BFS) or on a DAG (where an optimal path can be found by considering ...

Solution approaches to find a pair with a given difference Here, we will be discussing two approaches for solving the problem. One is brute force & other is an efficient one. Bruteforce approach In the brute force method, we need to find each pair and its difference to check whether the ...
For example, if you are given the digits 0, 1, 2, 4, 6 and 7, you can write the pair of integers 10 and 2467. Of course, there are many ways to form such pairs of integers: 210 and 764, 204 and 176, etc. The absolute value of the difference between the integers in the las...
The major difference between BFS and DFS is that BFS proceeds level by level while DFS follows first a path form the starting to the ending node (vertex), then another path from the start to end, and so on until all nodes are visited. Furthermore, BFS uses the queue for storing the ...
In the brute force method, we need to find each pair and its difference to check whether the difference is the same as the input one or not. Since we need to find each pair difference thus the time complexity would be of O(n^2)....
