Hey guyz that's not good u should appreciate...I found here 5k views but it has only 89 likes ...🙄🙄🙄at least u should give like for his hard wrk he is doing really Awsm thnku sir🙂🙂
Awesome work sir really hands off , you have a good concept .
Excellent Explanation Sir. Very useful..
Well explained each steps.
Thank You Sir for this Course.
Sir please make a video on file handling in java by the way great work and easy to understand
I think, according to BODMAS, Division has a high priority than Multiplication. so I got ABCD/*+. Can any one justify?
Division and multiplication have same priority .
Superrrrrr explanation sir your lectures are awesome
your teaching are nice
very well explained sir
Sir videos on graphs kuda cheyandii
I would appreciate if anyone could answer this. At 16.50 min at particular example I'm little confused about POSTFIX converstion:
Expression: A + B * C/D
I'm expecting the POST FIX EXPRESSION: AB+CD/*
But why it has to be ABC*D/+ ....
Can anyone help me understand this ?
According to infix to postfix conversion schema -> operands get added to the postfix expression -> operators check some conditions first; if the stack is empty the character gets pushed into the stack, it not then it checks priority and that's a pretty lengthy explanation. In your case, I'm just pointing out one err -> till reading B your stack should be like this |+| (imagine it horizontally for now) after that when you read asterisk(*) it compares with the top of the stack, and if reading character has greater precedence then character at the top of the stack then that char gets pushed up in the stack. Now, the stack looks |+ *|, C now is another operand so it will definitely be added to the postfix expression, thus ABC...
For better understandability I would recommend Sundeep sir's lecture on it, just scroll a bit higher from this playlist from here and keep learning 🙂
Thank you!
Sir kindly take my advice,
I am not a experienced one but,ur videos are long and slow....U should speak fast and quick and speak precisely.
This generation needs crisp concepts.
Eventhough ur concept clarity is good,u won't reach a higher no of subscribers if this continues.....
Kindly take my advice as a friend
Well done sir, how can I get your videos that explains converting from tree to expression in postorder, inorder and pre-order
Thanks thanks thanks a lot sir
👍🏻
👏👏👏👏🙏🙏
God bless Sundeep
Sir last step m post fix ki jgh infix hoga
Sir how you write expression in postfix???
Sir please check postfix expression is wrong
Bro while reading character starting itself operator comes wat to do Bro?
Gud....but i need code for this
AB+CD/* is the correct postfix expression
yes
No
Check the rules once
@@saikiranmaragouni1364 bro what is rule please explain me
@@hrxhrx3947
1) lower priority operators(+,-) can tolerate higher priority operators(×,÷,^)
Eg: you can keep +× but you have to pop × if it's ×+
2) Two same priority operators can not tolerate each other.
Eg: ×÷ in this you have to pop × before inserting ÷
Therefore the correct postfix answer for
A+B*C/D will be
ABC*D/+
Code sir
Post fix expression is wrong
ABCD/*+
Hi
Please let me know the correct one.
ABCD/*+
@@sundeepsaradhi AB+CD/* is the correct postfix expression sir
@@sundeepsaradhi ur correct sir
@@sundeepsaradhi ABC*D/+
