thank you mam it is very helpful

[@sivabunny2809]

Mam TQ u so much

[@ramankr0022]

3:26 if we take out first two elements.. shouldnt it be 4/12 instead of 12/4 ? thanks for the video.

[@priyalsarda9470]

No. The top element goes after the operator and next popped one goes on left of operator

[@user-jd6sy4yb4l]

Mam Explanation is nice

[@aadhithyaarun5605]

Mam i have a doubt.. When dividing the top most values 4&12 it has to be done as 4/12 or 12 /4 which one is correct?

[@szehaohar]

this confuse me tooo

[@shivaprasadsubedi]

If it’s evaluating prefix expression then u do 4/12, but while evaluating postfix expression u do 12/4.
For prefix the order is (1st top element-operator-2nd top element)
For postfix the order is(2nd top element-operator-1st top element)

[@krithikar.g2364]

12/4 because 4 is top value with that you have divided 12

[@darshananaik8136]

thank you sis

[@misbakhanum433]

Thank u so much mam 💓

[@rajiyashaik6123]

Thankyou mam

[@Codev17988]

Well deserved 👏

[@maitriyeeray]

Thankyou ❤️

[@amit80086]

Mam why shouldn't it be 4/12....in place of 12/4 at 3:41 .....this problem is faced in division and subtraction

[@kingofshadow8222]

I agree with you please maam tell us!

[@sidharthsinghania5931]

Keep it as simple as possible, 4 /12 will give output in Decimal so 12 /4 and there's no problem in doing it.

[@sidharthsinghania5931]

And btw first operand pushed in stack will be operated with the operand on the top of the stack so first 12 was pushed then 4 was at the top of the stack so 12 /4. If 4 was pushed 1st and 12 would be at the top then I believe that would have happened the case you mentioned above

[@alicia420]

thank u so much

[@harshalparekh6452]

in the last (-) operator, shouldn't it be 3 - 40 instead of 40 - 3 ? at Time 3:40

[@venkateshvenky2880]

no

[@Sunder_Verma]

No, like it's 12/4 not 4/12.

[@KaranChugh-gt9ji]

Thnx mam

[@senior9563]

helpful video thank you

[@AnkitKumar-ue3rr]

Thanks Mama

[@elliotho3015]

Thank you :)

[@manojkumargv6931]

Thanks ☺️

[@sangeethasambath2861]

Mam if we divide 4 by 12 the answer changes know mam??? How r u saying that 12 is divided by 4

[@rubeenaartista1371]

Thank you🌹🙏🙏🙏

[@Homelander_0819]

Watching this video for the 2nd time after 6 months 🙃

[@pavankalyan1960]

Mam in the stack you placed 40,12,4 and as per the next operator / we have divided 12/4 which is divisible. What should we do if we get a non divisible number

[@UrvashiJoshi975]

May be we’ll ignore the decimal part

[@narein2372]

what to if $ symbol is given

[@cr7messy22]

Nice mam 😊

Wohoo

Tq mam

[@futurehokage8673]

what about the precedence? Didn't we have to evaluate / and * first???

tq aunty

[@SalmanKhan-bt4no]

great

Mem aapne 12 ko ek sath kyo liya isme to har ek symbol alag alag liya jata h jese 12 ko lena tha 1,2

[@safeerahmedx11]

What if $ is used

[@hazem8278]

thanks

[@viratkohli2616]

At 3:25 madam why you not take 4/12 instead of 12/4 explain someone please

[@sparkindness]

Why are u taking 12/4 only taken also 4/12 is it correct

[@kong9748]

Thank

[@anvesh5377]

3:29 when u pop the elements that will be like this 4/12,but how 12/4 plz tell me😓😓😓😓

[@easyprogramming3019]

Same doubt

[@dirisalapriyanka]

If it’s evaluating prefix expression then u do 4/12, but while evaluating postfix expression u do 12/4.
For prefix the order is (1st top element-operator-2nd top element)
For postfix the order is(2nd top element-operator-1st top element)

[@msr3171]

@@dirisalapriyanka sorry.. It's not clear can you explain it once again

[@powerking6437]

@@msr3171 bro madam said that take top most 2 values in the stack in that's top value 1 always should noating operand 2, following value 2 noates operand 1 then we perform operation =operand 1(-, /, +, *) operand 2 hope u understand 🤗🤗
