給定{v1, v2, v3, v4, v5}鄰接矩陣（adjacency matrix）如下，則 v1 到其他各點（可以經過別的點）的最短路徑距離何者正確？ $$\begin{array}{ccccc}\text{v1}& \text{v2}& \text{v3}& \text{v4}& \text{v5}\end{array}$$ $$\begin{array}{l}\text{v1}\\ \text{v2}\\ \text{v3}\\ \text{v4}\\ \text{v5}\end{array}\left[\begin{array}{ccccc}0& 1& 3& \infty & \infty \\ 1& 0& 1& 2& 6\\ 3& 1& 0& 1& \infty \\ \infty & 2& 1& 0& 1\\ \infty & 6& \infty & 1& 0\end{array}\right]$$
