Postfix to Infix Conversion | Examples | Data Structures | Lec-17 | Bhanu Priya

[@songanon]

For those confused on what to do first when it comes to - and / . Just remember how it got to the stack to begin with. Take this simple infix expression of 5- 4. When converted to postfix is 54- . You placed the 5 first in the stack, meaning it will be the last thing taken out. Hence when converting this the 5 will be at the bottom. So when taking two out of the stack , always use the last one first :). That also works with division. Addition and multiplication obviously doesn't matter but technically the same applies

please

[@abirmazumdar2833]

Thank you bro

[@JainHruday]

[@lolpro5922]

Thank you 👍🏻

[@songanon]

Also ! When popping the last two of the stack imagine your creating another stack when your popping , this is why it seems like the bottom value is used first , because it is now atop of a new stack you created

[@MohammadZulfikar]

Correction**: Real in-fix is: (A-B) / ((D + E) * F) N.B. Correct me if I am wrong.

[@090-jellabharath2]

Yes u r right

[@ansharora9331]

You're right

[@kamunikarthik9630]

Yeah

[@Shanu_1113]

Yep

[@sereiin120]

Yeah you are right

[@vanamgangireddy6067]

there is confusion regarding use of A-B or B-A as of me the clear explanation is if we encounter an operator then pop two elements A,B i.e., B->top element of stack, A->next to top element and result=A operator B (lowerone operator upperone)

[@nithindreemendis875]

Yeah the bottom one is supposed to come first. For example is a stack has 10 (at the top) and 18 next then you do it as B - A, so its 18-10.

Thank u mam it's really very helpful for everyone who got classes boring by the Teachers.We clearly understand by your class mam, Thank you very much mam

[@ProudiPhoneOwner]

Thank you so much for the clear explanation!!!

[@Rakesh36oi]

Mam it is very helpful.... thanks....but you did little mistake at line no 9. at the line no 8 you have written ((D+E)*F) and at the line no. 9 you have written ((D+E*F)) which is completely wrong. answer should be (A-b)/((D+E)*F)

[@marchanselthomas]

even I'm wondering the same I got the same as you

[@Beatsbasteln]

i really like your videos both on postfix to infix and infix to postfix conversion, but what makes this difficult to me is that you only use binary operators with the common associativity rule and you avoid x, which is why you can evaluate the expression everytime an operator occurs

[@maheswarig7405]

But according to stack, the output should be, (F*(D+E))/(B-A)

Vo prefix to infix ma hota hai

[@sportsman702]

well if you reverse the answer, you get the infix

[@chanakyakoilada204]

Tq madam itsvery useful for me but i think there is a mistake at 3rd line too at 2nd line u said (A-B) according to the ex. U have give (10-2) i think so it should be ( B-A) could you please tell me the technique i am so confused

[@stankafan6688]

bro it will be (A-B) only that is the lower operand - upper operand

[@taciturn9027]

If stack contains elements A and top as B,u wrote A-B then if there is 2 in A's place and 10 in B's place...how can u write 10-2? 🤔🤔 From A-B....u should write 2-10 right?

[@ashajyothisagireddy8090]

In postfix expression we have to take top of the stack is operator 2...but while evaluation consider op1 - op2...

[@darkben20]

thank you, that was very explanatory

[@molamola8305]

Its wrong conversion.Convert it back into prefix and you won't get the same.

[@mrinmoyhalder7293]

If A < B then (A-B) will be -ve, does stack allow -ve element. suppose in a conversion of Postfix to Infix consists of numbers it will create a confusion that we have to perform (A-B) or (B-A), I mean in which order the element will be popped when seeing a ' - ' sign.

[@abdiladifmohamud5957]

Why is it that the madam used B operand A for all steps but the last step she used A operator B. what I mean is she operated what was on top of the stack with another but the last step she operated what was at the bottom with the other.
