[@SamiKhan-kg7jm]

bhaee kia kahny ;-)

[@ajaysrailzoneofficial]

If brackets are given what to do

[@badmon7759]

Infix to postfix gets rid of parenthesis, but retains order of operations. There should be no parenthesis by the time your expression is in postfix.

[@ankitathakur5989]

Tnx mam ji

[@yashbhardwaj8510]

Hi Jenny, I watched almost all the affix videos, could find one where you explained it programatically. Also, I'm missing resolving an infix expression using stack

[@anujjadhav2771]

infix won't need stack to solve, infix is already in the simplest form

[@kusumaseera3753]

Mam.. missing some concepts I mean u said that next video will be the construct a binary tree using prefix expression but in the playlist didn't have mam.. please upload the video .and in the playlist missing some order please check . Thank you:)

Great very helpful But we need Example of code so Try please .U r doing well :)

[@harrysingh9571]

Hey mam. Can u make some videos on icse bluej java programs please

[@Nautyy9]

Mam do we need to create a current node which point to the operator having both child i.e, right and left subtree to store that operator into the stack ? I mean in binary tree we have to pointer that is left and right since both have some values then do we need to create a temp or current node whose one pointer point to the operator and other to stack ? Plzz reply

[@alphonseprakash7459]

Mam at last of your video you said that you will upload a video for conversion of prefix to tree but i cannot find that video in this playlist.... please upload it....

[@ranitrianigustia]

how if the operand there are 3 operand last and 3 operator last node? That is need balancing ?
