You've got another problem dealing with arrays. Let's consider an arbitrary sequence containing n (not necessarily different) integers a₁, a₂, ..., a_n. We are interested in all possible pairs of numbers (a_i, a_j), (1 ≤ i, j ≤ n). In other words, let's consider all n² pairs of numbers, picked from the given array.

For example, in sequence a = {3, 1, 5} are 9 pairs of numbers: (3, 3), (3, 1), (3, 5), (1, 3), (1, 1), (1, 5), (5, 3), (5, 1), (5, 5).

Let's sort all resulting pairs lexicographically by non-decreasing. Let us remind you that pair (p₁, q₁) is lexicographically less than pair (p₂, q₂) only if either p₁ < p₂, or p₁ = p₂ and q₁ < q₂.

Then the sequence, mentioned above, will be sorted like that: (1, 1), (1, 3), (1, 5), (3, 1), (3, 3), (3, 5), (5, 1), (5, 3), (5, 5)

Let's number all the pair in the sorted list from 1 to n². Your task is formulated like this: you should find the k-th pair in the ordered list of all possible pairs of the array you've been given.

The first line contains two integers n and k (1 ≤ n ≤ 10⁵, 1 ≤ k ≤ n²). The second line contains the array containing n integers a₁, a₂, ..., a_n ( - 10⁹ ≤ a_i ≤ 10⁹). The numbers in the array can coincide. All numbers are separated with spaces.

Please do not use the %lld specificator to read or write 64-bit integers in С++. It is preferred to use cin, cout, streams or the %I64d specificator instead.

In the single line print two numbers — the sought k-th pair.
