write a more detailed version of Dynamic programming algorithm for the traveling salesperson problem (Algorithm 3.11).

Algorithm 3.11 The Dynamic Programming Algorithm for the Traveling Salesperson Problem Problem: Determine an optimal tour in a weighted, directed graph. The weights are nonnegative numbers. Inputs: a weighted, directed graph, and n, the number of vertices in the graph. The graph is represented by a two-dimensional array W, which has both its rows and columns indexed from 1 to n, where W [1] ) is the weight on the edge from ith vertex to the jth vertex. Outputs: a variable minlength, whose value is the length of an optimal tour, and a two-dimensional array P from which an optimal tour can be constructed. P has its rows indexed from 1 to n and its columns indexed by all subsets of V - {01}. Pl [A] is the index of the first vertex after vi on a shortest path from v; to v that passes through all the vertices in A exactly once. public static number travel (int n, number (0) W index P) { index i, j, ki number minlength; number O) D = new number 1..n] [ subset of V - {}]; for (i = 2; i
