Programming Challenge – LeetCode: Bellman Ford C # Network Delay Time

There are N network nodes labeled 1 through N.

Given times, a list of travel times as directed edge times (i) = (u,
v, w), where u is the source node, v is the destination node and w is the
Time it takes a signal to get from the source to the destination.

Now we send a signal from a certain node K. How long will it take
all nodes to receive the signal? If this is not possible, return -1.
Enter the image description here


  1. N is in the range (1, 100).
  2. K is in the range (1, N). The
  3. The time period is in the range (1, 6000).
  4. All edge times (i) = (u, v, w) have 1 <= u, v <= N and 0 <= w <= 100.

Please check the performance

Learn affiliate marketing
Extensive courses and training to learn step by step how to build a business and earn revenue with affiliate marketing

what you will learn

Affiliate marketing can be addressed in several ways.
Unfortunately, much of the information on how to build a business does not teach affiliates.

Too many affiliates are stuck in the hamster wheel of affiliate marketing. They make it great for a while, then they dry up and they start all over again. To make matters worse, they usually use methods that do not really build anything valuable.

I decided to teach affiliate marketing methods that did not focus on promoting "sketchy" programs or applying "blackhat" methods. I teach methods that bring stable income and grow over time. You do not want to be the person who does a lot of hard work, but has nothing to show for it at the end of the day. Affiliates are notorious for being middlemen who do not produce anything of value, but it does not have to be that way. You can make a lot of money while building real assets that will generate revenue in the coming years.
In Aff Playbook classes, you'll learn how to run affiliate marketing as a long-term business that is growing steadily

Learn how to create and monetize websites, how to choose affiliate offers and slots, how to use paid traffic to your advantage, how to create websites, and much more.
You will not learn just one thing.
An intelligent affiliate marketer focuses on tapping into multiple revenue streams. I will teach you how to do that and avoid putting all your eggs in a basket.
I focus on creating systems that you can learn, implement and create yourself. You'll find content and strategies with specific steps to follow. I do not waste time with "fluff".
There are so many great ways to do affiliate marketing. Some people only focus on affiliate marketing, others use affiliate marketing only as part of their business.
Aff Playbook helps you figure out where to start or how to integrate affiliate marketing into your existing business.


Algorithms – Bellman Ford – negative cycle

This is my code for detecting a negative cycle in a graph using the Bellman-Ford algorithm, but I can not figure out why it returns an incorrect answer

public static final int INF = Integer.MAX_VALUE;
private static int negativeCycle(ArrayList() adj, ArrayList() cost) {
    int dep() = new int(adj.length);
    for(int i=0; i dep(j) + cost(j).get(v_index)) {
                    dep(v) = dep(j) + cost(j).get(v_index);


    for (int j = 0; j < adj.length; j++) {
        for (int v : adj(j)) {
            int v_index = adj(j).indexOf(v);
            if (dep(v) > dep(j) + cost(j).get(v_index)) {
                return 1;

    return 0;

ford fulkerson – Maxflow of the graph equal to the flow value plus maxflow of the residual graph

I check the max flow min cut for an upcoming exam, and one of the proofs is based on the fact that it is used for each flow $ f $ in the graphic $ G $ and rest graph $ G_f $,
$$ maxflow (G) = value (f) + maxflow (G_f) $$, That seems intuitively true, but I can not prove it. Any help would be appreciated!

Algorithms – why not use Dijkstra Algo + Bellman Ford's last line instead of Bellman Ford

correct me if wrong
1. For a given chart, use dijkstra on it.
2. Now after v-1 iterations or after finding all possible minimum distances for each node.
3.check for each edge (u, v) in the graph
if (vd> u + w (u, v))
then you return wrong
Here the temporal complexity is lower than with bellman ford and also negative cycles are considered

Graph Theory – Is there a Ford Fulkerson run for each flownet in which all extension paths consist of forward edges only?

Is there a Ford Fulkerson algorithm for each flownet in which all extension paths consist of forward edges only?

I've seen this claim for a flow network where all edges have c (e) = 1, and I tried to find a counter example for networks with different capacities, but could not.

Is this statement always correct? and if so, do we need reverse edges just because we can not know which paths have only forward edges while we are executing the FF algorithm?

Many Thanks!
