Yes, sorry for the confusion

You can chose randomly(any one of them) then.

Sir ans ...alag aa rhe hai ...as I took the first zero from the dummy column ...but in book they have choosen the last zero from the dummy column

​@@thekrishnasuribut thank u so much sir ...for atleast answering to my doubt ....hats off to you 😊💕✨..and thank u so much for making vedios on these topics ...u have really explained the concepts so well ....May u achieve greater heights 💯✨

@@Harshi1823 yeah it's possible ans can vary, But, when you'll apply MoDI method to it, you'll get the final answer same in all the cases😊. Because MoDI method will give the most optimal answer. It's not wrong if you getting different ans after applying LCEM ONLY.

But your calculations and the way should be correct😊

No, in planar graph, edges can't cross/intersect each other.

Sir mn 2din sy apka lecture lay rehi theory samj a jati likan question ka issue h

Sure, going to cover more questions in the upcoming lectures. Join our Telegram channel (link in description) for practice questions and more.

Ok shukria​@@thekrishnasuri

Still u having doubt in it?

Yes ​@thekrishnasuri

Let me Break it down into simpler steps: 1) Make Adjacency matrix of a graph given to you (this would become your 'A') 2) Now check how many vertices you having in your graph (this would become your value of "m") 3) Once you got the value of "m", put it into the the equation and solve it simply. Equation : B=A + A^2 + A^3 +.....+A^m 4) After obtaining the B matrix by doing all the calculations, you have to make Path Matrix "P", The Non zero values in matrix B will become "1" in matrix P, and all other will be treated as "0" only. Now your Path Matrix "P" is ready. Let me know if still any doubt

Ye hum B equation ki calculation kis trhn krei gei ismy thori problem aa rhi ha

@@WajihaNadeem-y3r In this particular question which is covered in the video Its simply matrix calculation B = A + (A×A) + (A×A×A) Because value of m=3, So maximum power of A would be 3 only.

Self loop confuse kur reha h k kub ish ko 2 consider karna h ?

@AbdulAllah-en4vx always remember, jb bhi self loop ko as an edge count krna h to it will be counted as 2. You can imagine like, for example, if A is having self loop, then that self loop edge is once acting as outgoing edge(from A) and at the same time acting as Incoming edge(to A). This way it'll be counted as 2. Is that clear now?

@thekrishnasuri g jazakAllah

Yes

Dummy row/columns wouldn't be affected while converting max to min problem. You can either make it balanced first or can convert into Min first and then balance. 😊

No, both are different methods for different purposes.

You being confused buddy, Its *0* when there are 2 same *MINIMUM NUMBERS* as we have to see the difference between 2 minimum numbers. If there has been { 30,8,8} then p shall be '0' but here's, as you said, { 30, 30, 8}, see two numbers which are minimum, i.e., 8 and 30 ( 1st least number =8, 2nd least number = 30) so the difference will be 22😊 Hope so you understood.

@@thekrishnasuri , 😁 Got it, It's my mistake, I was confused. Thanks for the clarification!

Yes, thank you so much for correcting me and sorry for the confusion. 😊
