[@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]

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]

[@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

[@prasannavenkkatesh1192]

do we need 2 stacks?

[@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.

[@jagan2350]

Your videos are awesome 🔥

[@helloworld4788]

thank u so so much for the explanation

[@iamnoob7593]

Brilliant and Intuitve.

[@abhaykumarsingh3884]

Very good explanation..

[@navraj1995]

i wish there was explantion of actual code also..

[@tusharrastogi7490]

great explanation :)

[@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.

[@tanyatanya3100]

nice explanation!

[@subee128]

Thank you

[@atharvdeshmukh8192]

how to handle multidigit number?

[@nikoo28]

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

[@ousmanbah10]

best explanations

[@nikoo28]

Keep watching

[@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.

[@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)

[@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.

[@thanhnguyenduy78]

[@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
