Let G = (V, E) be a directed graph with n vertices. A path from v

$$$A[j,k] = \left\{ {\matrix{ {1\,if\,(j,\,k)} \cr {1\,otherwise} \cr } } \right.$$$ Consider the following algorithm.

_{i}to v_{j}in G is sequence of vertices (v_{i}, v_{i}+1, ……., v_{j}) such that (v_{k}, v_{k}+1) ∈ E for all k in i through j – 1. A simple path is a path in which no vertex appears more than once. Let A be an n x n array initialized as follow$$$A[j,k] = \left\{ {\matrix{ {1\,if\,(j,\,k)} \cr {1\,otherwise} \cr } } \right.$$$ Consider the following algorithm.

```
for i = 1 to n
for j = 1 to n
for k = 1 to n
A [j , k] = max (A[j, k] (A[j, i] + A [i, k]);
```

Which of the following statements is necessarily true for all j and k after terminal of the above algorithm ?2
