UPDATEIT - Update the array !
You have an array containing n elements initially all 0. You need to do a number of update operations on it. In each update you specify l, r and val which are the starting index, ending index and value to be added. After each update, you add the 'val' to all elements from index l to r. After 'u' updates are over, there will be q queries each containing an index for which you have to print the element at that index.
Input
First line consists of t, the number of test cases. (1 ≤ t ≤ 10)
Each test case consists of "n u", number of elements in the array and the number of update operations, in the first line (1 ≤ n ≤ 10000 and 1 ≤ u ≤ 100000)
Then follow u lines each of the format "l r val" (0 ≤ l, r < n, 0 ≤ val ≤ 10000)
Next line contains q, the number of queries. (1 ≤ q ≤ 10000)
Next q lines contain an index (0 ≤ index < n)
Output
For each test case, output the answers to the corresponding queries in separate lines.
Example
Input: 1
5 3
0 1 7
2 4 6
1 3 2
3
0
3
4
Output:
7
8
6

Solved without using bit. O(n) solution.
