6 years after this video has been published , still it saves engineering students
@walkman 12/June/2020 computer science student saved!
True m alive
@walkman who was killing you in lockdown

For those who disliked, you can not get better then this.

Are you getting the solution... subtitle is distributing it is at wrong location
than*
.............
I agree with you
true, but people dont value free things, they will like half this quality if they have to pay a hefty fee for it, and regarding location of subtitles, one can just switch them off if they distract...

In the while loop why the !s.empty is used, the stack is initially empty and the condition fails in first iteration
Just to note, combining this lesson with the previous lesson you can make a working calculator.
what previous video
i just wonder , if you wouldn't have made this videos , then i would have been literally ended up just cramming the stack , que ,etc from any local author! but the flow of your explanation is indeed dulcet ! thanx a lot for employing your time to help students like us !
I see o.O !
You just saved me from jumping off a building.
Thanks mate.
people jumping off cuz they didn't understood a topic,awesome
The real beauty of the video starts around the 12 minute mark with the parentheses. I couldn't, for the life of me, find a way to work with parentheses, but when he did his excellent job explaining it I was finally able to work it out.
Congratulations on your videos. I'm studying in an university and your videos are much easier to understand. Thumbs up!
the USA hav Stanford
India has mycodeschool
But, thankfully, the whole world has mycodeschool!
I am speechless by your understanding of data structures , so clean apt and to the point , a huge thank you really
By far the best infix/prefix/postfix series on TH-cam
Clear, crisp, precise and concise. You and your content are amazing! Thanks!
Thank you! This lesson was very clear and easy to understand.
Thanks. This was a terrific explanation of the conversion.
Well done! This is the clearest explanation of this topic that I have ever seen. Thanks so much for sharing.
@mycodeschool, please make more videos! I haven't seen a better explanation to this conversion. By far the best!

@@saireddybonthu985 That case is handeled at the last else condition where we append all teh leftover operators to the string form the stack.
Great Explanation man. Everything explained in one video concisely!
This lesson is going to live forever helping future students! Thanks.
I needed to brush on this stuff recently, thank you so much for posting this clear example.
Thank u Sir, my school teacher just made me to cram this, nut now i really understand the concept.
MAY GOD BLESS YOU..
duude such a great clear explanation, still helpfull 9 years later, thanks a lot 👍
Excellent video, couldn’t ask for a better explanation!
RIP Sir, You are not with us but your legacy will live forever.
@@zuhail339 what happened how??
What??? Did he die????? how????
@@antojosu That's his friend (the co-founder of this channel) not him
@@MohamedHossam-in1yn Oh
simple and outstanding ,cant have better videos on infix and postfix than this.
omg，teacher，you are so much better than my professor，i become more confident after seeing your videos
these are quite difficult but you made them easier for all of us !! Thanks for such kind effort but I'm still struggling with this algorithm since morning.Somehow my mind is muffed :(
I understand what to do with my project now. Thank you for explaining it well!
wow..! what an explanation it is! Really great.if this video doesn't exist i might have left stack topic for sure.
intelligence of the guy teaching is very well visible through his lectures
these videos are GOAT on data structures
Your videos are worth Watching. Thanks for uploading them.
even in 2019 your maths is still appreciated. THANK YOU !!
Stupendous explanation and great illustration
big thanks, this has helped me so much in short amount of time!
I remember watching this video when I was in 11th and now I am watching this again in my second year . DAMN
You are doing the Lord's work, even in 2021
this video was uploaded on 2013 but still in 2020 this is the best explanation
you are simply the best at explaining!!!! thank you

Thanks a lot.
thank you
thank you bro your a real life saver
very nicely and smoothly explained.Thanks
Thanks a lo0Oo0Oo0Oo0Oo0Oo0Oo0Ot for your great videos :)
Note: breaks are missed in switch case in GetOperatorWeight function which leads to ignoring arithmetic precedence - Because returned weight will be 3 in the all cases -
Really nice work the best I've found I can now start with my project Thank you
thank u sir for making my exam more simplest
Super understandable! Thanks, this video really helped me with my project :).
Wow!! Really awesome explanation :) Lots of thanks!
24/03/22 and it still saved me
This is the best video for infix to postfix
Found it really helpful!! Thank you :)
Most excellent teaching. Thank you.
Really clearly explained
How someone can dislike these gem videos
Omg I now understand hurray! All credits to u sir 😊
Thank you.
I dont understand English but i understand algorithm.
You are the best👍

his friend died not he
Excellent lecture, thanks so much
clean simple explanation...thank you. :)
You're the best Dude!!! Keep up
amazing video !! good explanation..
Nice one, clearly stated everything
Thanks for clearing my confusion
Thank you! I really understand this now!
@ 7:42 what it mean? there r 2 ways in which we can find the end of the right operand for an operator a)If we get an operatoer of lesser precedence
Thank you so much! This is very useful.
Subscribed. Great video.
This was great, thank you.
easy to understand nd hard to 4gt....awsmmm xplaintn :)
great explanation as always .... Lots of thanks for your videos.
thnx for uploading such video. very helpful
Well Explained!
Thank you sir :)
pseudocode was very tough nd explained so quickly..however logical view was gud
Excellent explanation ----> 5 STARS
GREAT! now my code works! THANK YOU!
different from how i did it, but your explanation has clarified and helped me successfully debug!
Best video for explanation :)
i just love you sir.
Sir I dont understand . plz explain - if(op == "$") . in your code ...
Great explanation.
really i have understood how to convert infix to postfix.
YOU ARE THE BEST. THANK YOU :)
Thanks a lot for your great and helpfull vedios
very easy to understand,thank you
very good explanation.
thanks sir...i wish you were my professor

@Edijing Edijer gosh.... please say u r joking
@@abdulrahmanyasser3897 sorry bro but this is the reality!!!!!... That's why they stop uploading videos
2014 Passed out, still remembered
no one can teach better than this!!!
Great tutorial. thank you sir
What changes need to be made to this approach for working with multi-character operands?
wow awesome ^_^ thank you so much
How do you know in the function hashigherprecedence which is the s.top() if the stack hasn't been populated????
thank you .Lots of love
R.I.P! Your videos will survive
Thank you so much from Vietnam
Can you make a video by dividing a column into
scanned | stack | expression
its very clear. its easy to understand. Thanks
