ADSPROP - Ads Proposal

no tags 

There are N customers set their M different advertisements on Baidu. Each advertisement is owned by single customer. The ads system of Baidu records the number of clicks of each advertisement this year. The proposal system wants to analysis the advertisements about the relativity of the description length and the number of clicks of the advertisements. During the analysis, it is very important to do such a query to ask the total length of the advertisements with top K clicking times for each customer. You may assume the clicks of all advertisements are distinct.

Your task is to help Baidu to design this little toolkit.

Input

The input consist multiple test cases. The number of test cases is given in the first line of the input.

For each test case, the first line contains three integers N, M and Q, denoting the number customer, the number of advertisement instances and the number of queries. (N <= 100000, M <= 500000, Q <= 100000)

Then M lines follow, each line contains three numbers, U, C and L, indicating the owner of this advertisement, the clicks for this advertisement and the length.

Finally Q lines come. Each line contains only one integer K, representing the query for top K clicking advertisements for each customer.

All input numbers will be positive and less than 1000000000.

Output

For each test case, output Q lines, each line contains only one integer, denoting the sum of total length of the top K number of clicks for each customer.

O(N+MlogM+Q) gives me TLE, what is expected complexity?

Edit: Apparently some file contains thousands of testcases with low M. memset()ing an array gave TLE, filling it with 0's in for cycle i<M gave AC

what do you mean by

Caution: Some cases in input file have K > M also.

Re (by XilinX): In the problem statement I only state that K<=1e9.
