dijkstra gives shortest path from one node to every other node so why not just run dijkstra for every node and store them we will have time complexity of O(n^2 logn) and easier to impliment as compared to this. edit: learn this algo guys this dijkstra thing don't always work i learnt it hard way
@@omingole7304 actually the time compexity of dijsktra depends on edge, its i think O(E log v), and in complete connected graph edge can be in order of n^2, if there we want shortest path from every node to every other node then floys warshall performs better since its tc would be O(n^3) while dijkstra would be something around O(n^3 log n)
@@kushagra4401 no bro in case of dijsktra we can find for negative weight edges because of that it fall into TLE but for dijsktra actually it taking O(N*E*log(N)) time complexity and for floys warshall it will be O(N^3)
though i don't have much experience about java , but i have encountered some cases where my literally same code in cpp got accepted but my firned's java one gave tle.
Why cant we use dijkstra for all pairs? Instead of 1 as starting point, use which node you want to start with and perform pre-computation. For shortest distance between 2 and 5. Start dijkstra for 2 and pre-compute all nodes. It is working fine for me
You teach just like a friend does before exam day. Fast, exact and to the point. Awesome content!
well said :)
👏👏💯great content. Simple and to the point.
please keep making videos like these, thank you!! 💚
Thanks bro , COMPETITIVE PROGRAMMING to acha ho gaya apke video dek ke please open souce ka bhi guide kar do please
Competitive programming ka god 🙏❤️❤️❤️❤️

can u tell when djikstra does not work?

Love you bhaiya love you...
Bhaiya c++ me ek project bataiye na final year ke liye
Hum first hum first🔥
Nice explanation..thanks sir..
💛 => I have a suggestion, along with advanced graph algorithm video share 5 medium-hard quality problems links to practice.
Thanks belongs to infinity brother!

amazing content💚💚💚💚
One word for you only Great 👍👍👍👍
please reduce the music volume slightly. because it's covering your voice. nice work
Bhiya video ki frequency increase kr do please..
can i do competitive programming in java?? will i regret later for not choosing c
++? i am much interested in java , thus chose java.
though i don't have much experience about java , but i have encountered some cases where my literally same code in cpp got accepted but my firned's java one gave tle.
@@kushagra4401 oo..I see..
sir, how many videos are left for the graph?
Which software u use for these red lines???
Please make videos on bfs in 2d traversal

i guess its same thing

Bhaiya, when will you cover linked lists, binary trees?
not planning to cover them
