输入解释
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 Si and Ti (1 <= Si <= Ti <= 10^9), means i-th flower will be blooming at time [Si, Ti]. In the next M lines, each line contains an integer Ti, means the time of i-th query.
输出解释
