Query with the stack code

#1

I have a query like for :

Input: 1 2 2 3
Output will be: 2 2 3 -1 or 2 3 3 -1 or 2 3 -1 -1

Please explain this?

#2

@dhruvtrehan45 answer should be 2 3 3 -1
since 2 is greater than 1, 3 is greater than both 2’s and we don’t have any element greater than 3 so -1 for that.

#3

https://ide.codingblocks.com/s/317143 What is the error in my code then?

#4

it is said in the problem statement that array is circular so if you can’t find greater element in the right side of an element then search it from start to before that element.

#5

For 3 2 1 output should be -1 3 3 ?

#6

yeah this is correct
