      Question

      In which of the following scenarios would the

      Floyd-Warshall algorithm be most suitable?
      A Finding the shortest path from a single starting point to all other points in a very sparse graph with positive edge weights. Correct Answer Incorrect Answer
      B Finding the Minimum Spanning Tree of a graph. Correct Answer Incorrect Answer
      C Determining the shortest paths between all pairs of nodes in a dense network where negative edge weights might exist (but no negative cycles). Correct Answer Incorrect Answer
      D Searching for a specific element in a sorted array. Correct Answer Incorrect Answer
      E Optimizing a complex scheduling problem with many constraints. Correct Answer Incorrect Answer

      Solution

      The Floyd-Warshall algorithm is ideal for solving the all-pairs shortest path problem. Its O(V^3) time complexity makes it more efficient for dense graphs compared to running single-source algorithms multiple times. Additionally, its ability to handle negative edge weights (as long as there are no negative cycles) makes it versatile for various real-world applications like network routing and urban planning.
