They announced this on FB page- The solutions are visible until INOI I guess.
Lets say our array is {1,2,6].
Now-
upper_bound(5)=lower_bound(5)=6;
If array is {1,2,5,6}.
Upper_bound(5)=6, lower_bound(5)=5.
Upper bound = return element >x, lower bound = return element >=x;
Upper bound = return smallest element >x, lower bound = return smallest element >=x;
And also it works only if the array is sorted in ascending order.
I assume he at least know and has read through the basics and just needs an example illustrating them.
