Flowers--（树状数组，离散化）

Problem Description

As is known to all, the blooming time and duration varies between different kinds of flowers. Now there is a garden planted full of flowers. The gardener wants to know how many flowers will bloom in the garden in a specific time. But there are too many flowers in the garden, so he wants you to help him.

 

Input

The first line contains a single integer t (1 <= t <= 10), the number of test cases. For each case, the first line contains two integer N and M, where N (1 <= N <= 10^5) is the number of flowers, and M (1 <= M <= 10^5) is the query times. In the next N lines, each line contains two integer S[sub]i[/sub] and T[sub]i[/sub] (1 <= S[sub]i[/sub] <= T[sub]i[/sub] <= 10^9), means i-th flower will be blooming at time [S[sub]i[/sub], T[sub]i[/sub]]. In the next M lines, each line contains an integer T[sub]i[/sub], means the time of i-th query.

 

Output

For each case, output the case number as shown and then print M lines. Each line contains an integer, meaning the number of blooming flowers. Sample outputs are available for more details.

 

Sample Input

2 1 1 5 10 4 2 3 1 4 4 8 1 4 6

 

Sample Output

Case #1: 0 Case #2: 1 2 1

题目运用了树状数组的模式2，区间修改，单点求值，关键在于怎么离散化
