This question is actually the longest path from the start point to the end point.
However, since the weight value cannot be negative when passing through each point, we need to initialize 0 when initializing the distance from array d. The Bellman-Ford Algorithm Optimized in the queue is used to find the longest path, but there are still some details to be aware.
Of course we can choose d [n]> 0 when using this algorithm to jump out of the loop to reduce the amount of computing, but

The above DRPC example is just a simple example to introduce the concept of DRPC. Let's take a look at a complex example that really requires storm's parallel computing capability. This example calculates the Reach value of a URL on Twitter.
First, we will introduce what is the reach value. to calculate the
idea behind Thisproblem is Easy.key idea:use a max_reach[] array to record the maximum position the elements (before and include Elem ent i) could reach.max_reach[i]: Indicate how far we can reach from the elemenets (before and include element I). for(inti = 0; i ) { if(Pre_max i)return-1; if(A[i] + i >Pre_max) {Max_reach[i]= A[i] +i; Pre_max= A[i] +i; } Else{Max_reach[i]=Pre_max; } }1. At each position, we have a
values of Y from large to small to determine whether the leaf node can be reached by a certain policy of B, if it reaches the clear answer, it is the y weight of the leaf node to be enumerated (because it is from large to small enumeration ).
Now consider a leaf node, set to v. Whether V can be reached depends not only on X, but also on a's mood. x certainly wants to reach V, because V is the best choice so far, none of the above can be reached (othe

You said to the cashier mm, "Sorry, I don't want to buy it. Please refund me !" The cashier mm and PP are re

The strongly connected component refers to a sub-graph in which the vertices can reach each other in the graph G. If a strongly connected component is not fully contained by any other strong component, then the strongly connected component is the st
