Given an array of $$$n$$$ positive integers and an interval $$$[l, r]$$$, you need to pick some elements from this array so that their sum lies within the interval $$$[l, r]$$$.

Input:
The first line contains three positive integers $$$n$$$, $$$l$$$ and $$$r$$$. The second line contains the elements of the array.

Output:
Print one line containing an integer denoting the number of elements chosen and another line containing a space-delimited list of elements sorted in ascending order.

Note: If there are multiple solutions, print any of them.

Sample test case:

Input:

7 80 100
10 20 30 40 50 60 70

Output:
