You just saved me from jumping off a building.
Thanks mate.

[@chill_dude_743]

people jumping off cuz they didn't understood a topic,awesome

[@AbhishekRavalfuntwixt]

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 !

[@ishanpatel6583]

I see o.O !

[@cadeezra315]

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.

Just to note, combining this lesson with the previous lesson you can make a working calculator.

Congratulations on your videos. I'm studying in an university and your videos are much easier to understand. Thumbs up!

Are you getting the solution... subtitle is distributing it is at wrong location

[@AshwiniSingh27]

[@mbogniruvic9796]

I agree with you

[@abhisheksolutions3368]

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

[@aviralagarwal5871]

I am speechless by your understanding of data structures , so clean apt and to the point , a huge thank you really

[@SizzlerWA]

Well done! This is the clearest explanation of this topic that I have ever seen. Thanks so much for sharing.

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 -

I think that'll follow the same algorithm with the exception of "Scanning the array from last index, if it is operator and topOfStackOperatorIsNotOfHigherPrecedence then push otherwise pop and append.
