Interesting problem
By Romed, history, 6 years ago, In English

Hello everyone
I've come across this problem and I can't figure out how to solve it.
We have an array a of length N (1<N<60) . We write down average of all the sub arrays of a and sort them. The problem is what is the Kth number (1<K<2^N)
sample input
4 10
1 2 3 4
Sample output
8/3

What are the limits on the values of the array $$$a$$$?
