How to approach this without array
How to approach
Hey @aatish08
This is a simple array question. Please help me understand why you are trying to find another DS for this. Maybe I can help you better then.
Yup i know its an array question,but the explanation part says to not use array or list, That’s why i asked to do this without array
@aatish08
You can actually process the input as it comes, store nothing in the array and process the input on the go. Or you can use stack and queue as well.
If your doubt is resolved please mark it as cleared. Thanks and best of luck !!
