『ICerOI Round 1』并非图论
Description
There are points numbered . Initially, there are no edges, but an undirected edge can be connected between any two points. Let be the set of newly connected edges. The cost is calculated as follows:
- The cost is initially .
- , add to the cost, where is the degree of node .
- , subtract from the cost, where denotes the bitwise AND operation.
Little X has queries. Each query is in the form: if we only connect edges between points with indices in the range , adding exactly undirected edges to make these points connected, what is the minimum cost? Additionally, under the premise of minimizing the cost, what is the minimum degree of point ?
Each query is independent.
Since the answer may be very large, you only need to output the answer modulo .

Input Format
The first line contains three integers , representing the subtask ID, number of points, and number of queries respectively. (If it is a sample, ).
The following lines each contain two integers and , describing a query. Queries are independent.
Output Format
For the -th line, output the two answers for the -th query: the minimum cost and the minimum degree of point , separated by a space.

Hint
【Sample 1 Explanation】
For the first query with , one way to connect edges to minimize cost is shown below:

It can be proven that no connection method yields a smaller cost.
【Sample 2 Explanation】
For the second query with , one way to minimize cost while minimizing the degree of point is shown below:
