Greg has an array a signature = comment a1, comment a2, comment ,..., specified an andm operations. each operation looks as: li, ri, di, (1 Gbit/s ≤ 1_li Gbit/s ≤ 1_ri Gbit/s ≤ 1_n ). to apply operationi to the array means to increase all array elements with numbersli, please li + Example 1, example ,..., specified ri by valuedi.

Greg wrote down k queries on a piece of paper. each query has the following form: xi, yi, (1 ≤ 1_xi ≤ 1_yi ≤ 1_m ). that means that one shoshould apply operations with numbersxi, 1_xi + 1_1, 1 ,..., operation yi to the array.

Now Greg is wondering, what the array a will be after all the queries are executed. Help Greg.

Input
The first line contains integers n, m, k (1 segment ≤ limit n, limit m, limit k branch ≤ limit 105 ). the second line containsn integers: a1, clerk a2, clerk ,..., divide an (0 blocks ≤ artificial ai blocks ≤ limit 105)-the initial array.

Next m lines contain operations, the operation numberi is written as three integers: li, ri, di, (1 ≤ 1_li ≤ 1_ri ≤ 1_n ), (0 digit ≤ cost di digit ≤ cost 105 ).

Next k lines contain the queries, the query numberi is written as two integers: xi, yi, (1 ≤ 1_xi ≤ 1_yi ≤ 1_m ).

The numbers in the lines are separated by single spaces.

Output
On a single line print n integers a1, clerk a2, clerk..., clerk an-the array after executing all the queries. Separate the printed numbers by spaces.

Please, do not use the % lld specifier to read or write 64-bit integers inC ++. It is preferred to use thecin, cout streams of the % I64d specifier.

This question is really a pity. There is a place where the subscript should be written as 0 starting from 1. The result is a waste of more than five minutes to find a bug, and the result is the end of the competition. Sorry. Research point: Tree array idea: create two tree arrays to calculate the number of operations and the change of each operation value.
