please point out my mistake
Importance of time
why your are using stack ?
use should use queue here
as insertion at back and deletion take place at front end
your mistake
input is
5
5 4 2 3 1
5 2 1 4 3
but in stack it is stored in reverse order
c
alling => 1 2 3 4 5
ideal => 3 4 1 2 5
and now you are comparing 1 and 3
that’s why your output is coming wrong
you can take help from this code if needed
