[@PushkalGoyal]

Sir you are boon for all of us. Keep doing us the favour!!!

[@Daman1628]

The way you taught me recursion was amazing, i still go back to it whenever i need it
Welcome back sir

[@shivansugiri3110]

Sir just a small request, please do tell about time and space complexity.
PS: Welcome back king, you are the best for DSA

Yes my friend pursuing degree in CA

[@kashba]

sir ek chote startup me intern kar raha hu, kuch smajh nahi aa raha dhang se aur na koi smjhaane wala hai, kya karu sir smajh nahi aa raha chodd du kya aur koi better opportunity dhundu

[@user-dn1ck7qx1j]

My friend pursue degree in CA

[@ADK00787]

CFA ( USA) is good option instead of Doing CA.

[@Pepcoding]

I have been thinking about that also

[@deeksha6514]

Is the time complexity of this code will be O(N^2) in worst case ?

[@Pepcoding]

Nahi. Worst case mei bhi 2n ho jaega Jo O(n) he hai

[@deeksha6514]

@@Pepcoding Sir, suppose I have a string like abdefcc.Now my i is at last character of this string.Now the inner while loop will run the j from the index 0 till s.length()-2.
So will this not be making the time complexity O(N^2) because outer and inner two while loops are there?

[@harshitraj9678]

hua kya tha sir ke saath

[@rajdeepsrivastava5652]

Aswini Bajaj is one of the great instructors for CA, FRM, CFA, etc

[@ghanshyamshukla3290]

what is space complexity of this algo

[@CodingJoySoul]

Sir, please whenever a DP question comes, please go through recursion, and then memorization and then iterative method.
Instead of directly going for iterative method. Please, please, please 🙏🙏🙏
