一个二叉树旋转的问题,二叉树旋转的算法在图中怎么计算?

Problem Description
Given a connected, undirected, weight graph G, your task is to select a subset of edges so that after deleting all the other edges, the graph G is still connected. If there are multiple ways to do this, you should choose the way that minimize the sum of the weight of these selected edges.

Please note that the graph G might be very large. we'll give you two numbers: N, and seed, N is number of nodes in graph G, the following psuedo-code shows how to to generate graph G.

Here ⊕ represents bitwise xor (exclusive-or).

Input
Input contains several test cases, please process till EOF.
For each test case, the only line contains two numbers: N and seed.(1 ≤ N ≤ 10000000, 1 ≤ seed ≤ 2333332)

Output
For each test case output one number, the minimal sum of weight of the edges you selected.

Sample Input
6 2877
2 17886
3 22452

Sample Output
2157810
259637
1352144
