← Logic & PuzzlesWhich outcome occurs when a depth-first search algorithm encounters a graph with cycles?
A)Algorithm finds shortest path
B)Search halts immediately with error
C)Algorithm may enter infinite loop✓
D)Search becomes breadth-first instead
💡 Explanation
The algorithm may enter an infinite loop because the same nodes are revisited repeatedly due to the absence of a mechanism preventing re-traversal, therefore it does not halt, find the shortest path, or switch to breadth-first search, rather it gets stuck in cycles.
