Thanks a lot Sugandh, me makes feel there is still hope in this world and people can clearly see through the reality.

[@shrimpo6416]

Tricky question that got me thinking for so long. Great explanation and awesome code! I code in Python but your code is so clean and easy to understand that I feel can read Java now XD

[@CodeWithSunchitDudeja]

The question is based on Monotone stack, complete stack playlist is here kzbin.info/aero/PLEI-q7w3s9gQpqrVq_9VkYugtILlqSB1I

Glad you liked it

Thank you so much for the great explanation. I have one doubt when iterating through the stack in obtaining final output. so the stack consists of elements in descending order right and when we iterate through it does the stringbuilder not consist of elements in descending order but not ascending? how is the stack being iterated in bottom to top order here?

This question is a bit tricky ... And i found it hard to think.. Thanks for the video sir... Happy holi🥳

Sir plz sde roadmap pr ek video bna do

[@techmoon_]

Space complexity is O(1).

[@prakhartandon8288]

It will be 0(n) since we are using a stack of len close to n and two constant space arrs

[@priyadarshanr296]

do we need the visited array ? won't it work without that for(int i=0;i
