Hello Vijju123, I have been recently studying my computer subject (Out Of The Blue) so i had this chapter called
Data Structure , it had a term which i cannot understand and my teacher suck at teaching so if u could do the honorâs and please explain what STACK is?!
Access denied to the link. Is it from an on going contest?
You need karma to comment, upvote or ask questions.
You are storing only 1 teamâs name. What if the other teams name gets overwritten in the next input?
Imagine you keeping/stacking things one over the other. Condition is, you must take things out without making the entire pile fall. Where will you add new element? -At top of pile. Where will you remove an element from? Only top of pile. Is it possible to remove any element not at top? No, an element can be removed only if its at top.
This is the concept of stack. You can google for JAVA stacks for further methods.

For the RECTANGL problem out of JAN18, am I missing something? It seems as easy as checking if two unique pairs of identical numbers exist. This works in the code/compile/run with the given (and my own) test input. Am I looking at it too simple/is there an edge case?
I think I know where you are going wrong. But no discussion is allowed till contest is live. You can ask for help tomorrow, after 3PM.
No worries, I found my mistake :). Thanks for the comment.

You gain karma when other people upvote you, which is done when you do something good for the community.
