Given a list of words. Given three operations find out the minimum steps to reach from source string to destination string. Basically, -----/ this is the problem with some modification. For this question I said I will use graph traversal techniques. So, they started asking about BFS and DFS, when to use them.

Question

Accepted Answer

The question is about finding the minimum steps to reach from a source string to a destination string using three operations.

BFS and DFS are graph traversal techniques that can be used to solve this problem.
BFS is typically used when finding the shortest path or exploring all possible paths in a graph.
DFS is useful when searching for a specific path or exploring deeply into a graph.
In this case, BFS can be used to find the minimum steps to reach the destination string.
Create a graph where each word is a node and there is an edge between two words if they differ by one character.
Start BFS from the source string and keep track of the minimum steps to reach each word.
Stop BFS when the destination string is reached or all possible paths have been explored.
The minimum steps to reach the destination string will be the number of steps stored for that word.
