Suppose, there is an array of size N. Find number of elements are less than VAL. The array may contain duplicate values.

for example,

array = [ 1 , 2 , 3 , 1 , 2 ]

VAL = 3

So answer will be = 4.

Can it done by STL. (such as set/multiset ) in logarithmic time

I already googled it ,but failed to find solution with STL.

Thanks in advance.
