Coding Problems
Section titled “Coding Problems”Question 1: Supply Chain Optimization
Section titled “Question 1: Supply Chain Optimization”Q1: Optimize supply chain routes to minimize delivery time.
Solution (Java):
public int minDeliveryTime(int[][] graph, int source, int destination) { int n = graph.length; int[] dist = new int[n]; Arrays.fill(dist, Integer.MAX_VALUE); dist[source] = 0;
PriorityQueue<int[]> pq = new PriorityQueue<>((a, b) -> a[1] - b[1]); pq.offer(new int[]{source, 0});
while (!pq.isEmpty()) { int[] curr = pq.poll(); int node = curr[0], time = curr[1];
if (node == destination) return time;
for (int i = 0; i < n; i++) { if (graph[node][i] > 0) { int newTime = time + graph[node][i]; if (newTime < dist[i]) { dist[i] = newTime; pq.offer(new int[]{i, newTime}); } } } }
return -1;}Time Complexity: O((V + E) log V)
