[@ananyadas3257]

There is a comment issue in your pseudocode...The third condition says if there is "[". It should be "]"

[@nikoo28]

Thanks for the correction. You are right.

[@unknownman1]

You seem like a friend with whom everyone wants to spend more time. Nice explanation btw.

[@nikoo28]

[@rhythmbhandari8549]

Your explanations were clear and easy to follow, and the animations and examples you provided really helped solidify my understanding of the problem.

[@S3aw0lf]

After watching the video I had to work on it myself and i finally figured the code. Thanx for the video

[@shwetagupta8721]

wow nikhil, you explained so well, far better than many of the paid courses, loved your teaching skills.

[@shubhammanecr7]

Commendable explanation sir!! I just can say one line - Why fear when Nikhil Lohia is here.

[@nikoo28]

🤘

[@priyapriyamadhuri6546]

Hi nikhil sir, whenever i was searching for any coding questions if you're video is available for a particular question that time i felt so happy , because your videos are really "worth varma worth"😁😁

[@MrRahulmalik]

you are my new fav instructor after sumeet malik, keep making more videos regularly!
thanks alot.

[@nikoo28]

[@pratibhaverma2063]

Thank you sir.Very handy approch and explanation.

[@nikoo28]

You are welcome

[@motivationalquotes8545]

Very well explained I don't understand why their is less like to video

[@nikoo28]

i dunno either 😂

[@prateeksharma1047]

Anybody trying to understand `k = (k * 10) + (c - '0');`. Suppose there is a string like 54[a], we will need to create the number 54 from chars 5 and 4. So the equation helps in creating the correct number.

[@anushkakhandelwal-s4c]

You were phenomenal. Hats off sirrr!!!

[@nikoo28]

thanks for your kind words

[@sukanyaghosh24]

[@gitansh194]

such a clean explanation .............thanku sir❤❤

[@TalhaTabrez7]

keep up the good work!!

[@shaiksameer9659]

Your explanation is so clear that I have no need to watch another video on this problem. However Nikhil ,how to solve if the number is more than 9 i..e it may be more than 1 character to ad to the number stack ?

[@shashanksharma3111]

damn

[@jatin_9911]

thank you sir your explanation is great 🔥 🔥

[@prasannavenkkatesh1192]

do we need 2 stacks?

[@MsProtestante]

Hi! Congrats for your solution! I am struggling to understand this bit of code k = (k * 10) + (c - '0') I print line by line with SYSO but I'm still no able to get it. When printing I get the following :
when k = 1
(k * 10): 10
(c - '0'): 1
this is k: 1
Why k = (k * 10) + (c - '0') ends up with 1? As (k * 10) = 10 and (c - '0')= 1 why k is not 11?
Could you please kindly clarify it?

[@nikoo28]

The value of k = 0, not 1. :)
Also when we push in the stack, once again we change it to 0.

[@thanhnguyenduy78]

nice!!!!!!!!!

[@phucpt2k]

This solution doesn't work if the integer has more than one digit. e.g: 11[ab2[c]de].

[@nikoo28]

It will work..for your test case the output will be
abccdeabccdeabccdeabccdeabccdeabccdeabccdeabccdeabccdeabccdeabccde

[@kolawoleabdulrahman]

it doesn't work for me as well.

[@dinnydinesh-b5w]

you are osm thank you

[@car_holic1995]

i wish there was explantion of actual code also..

[@atharvdeshmukh8192]

how to handle multidigit number?

[@nikoo28]

the solution handles a multi-digit number, check the github link in description :)

[@11shivamAhir00]

thanks sir

[@sakibx0218]

Why we need to add another stack. Since get got first bracket that means if you say stack.peek() you will get the value. Its just waste of memory

[@nikoo28]

The space complexity still remains the same O(n)

[@Abhaykumar-lw7nr]

third condition will not right instead of "[" '']"

[@acxd]

can you do it using 1 stack!

[@iamnoob7593]

The solution here is more intutive. I would prefer using 2 stacks.

[@deepakffyt2844]

Abhi awaj bahut slow aaa rahi

[@ridj41]

the code is very complex and is not easy to understand after watching this video tbh, might have made the soln just like the code

[@kuldeepdiwakar1506]

Explanation is too simple

[@abhishekthakur7578]

bhai isse accha toh mike mat he laga
