1. **Objective:**
- Using the indicated link costs, apply Dijkstra's shortest-path algorithm to compute the shortest path **from D** to all network nodes.
- Complete the provided table with the computations, where:
- **d(x):** Cost of the least-cost path from the source node D to destination x during the current iteration.
- **p(x):** Previous node along the current least-cost path from the source D to x.
- **N' :** Subset of nodes whose shortest path from the source D is confirmed.

**Table for Computing Shortest Paths:**

| Step | N' | d(A),p(A) | d(B),p(B) | d(C),p(C) | d(E),p(E) | d(F),p(F) |
|------|----|-----------|-----------|-----------|-----------|-----------|

| 4 | | | | | | |
| 5 | | | | | | |

2. **Resulting Tree:**
- Illustrate the shortest path tree rooted at D, based on the data computed.

3. **Forwarding Table Creation:**
- Using results from steps 1 and 2, create a forwarding table consisting of two fields:
- **Destination**
- **Next Hop**

Algorithm : (1. Single-destination Shortest Path, 2. Bellman-Ford, 3. Negative-Weight Cycles), Dynamic Programming, RNA Secondary Structure Consider n airports, labelled 1 through n. Each airport maintains a number of direct flights to other airports, represented by an edge with an associated cost. Since travel is currently restricted, one may only book direct flights—no airports will perform any transfers. However, things are beginning to open up again and airports are being slowly cleared to process transfers. These are done in order of label, so the first airport to allow transfers is 1, followed by 2, and so on. Once an airport is allowed to take transfers, flights through that airport may be booked. For example, consider the scenario depicted in Figure 1. When all airports are closed to transfers, flights may only be booked between airports connected by an edge. Thus, a flight from airport 5 to airport 2 may not be booked. However, once airport 1 is allowed to perform…
