Lord Tirek is a centaur and the main antagonist in the season four finale episodes in the series "My Little Pony: Friendship Is Magic". In "Twilight's Kingdom" (Part 1), Tirek escapes from Tartarus and drains magic from ponies to grow stronger.
The core skill of Tirek is called Absorb Mana. It takes all mana from a magic creature and gives them to the caster.
Now to simplify the problem, assume you have n ponies (numbered from 1 to n). Each pony has three attributes:
Lord Tirek will do m instructions, each of them can be described with three integers: t_{i}, l_{i}, r_{i}. The instruction means that at time t_{i}, Tirek will use Absorb Mana on ponies with numbers from l_{i} to r_{i} (both borders inclusive). We'll give you all the m instructions in order, count how much mana Tirek absorbs for each instruction.
The first line contains an integer n (1 ≤ n ≤ 10^{5}) — the number of ponies. Each of the next n lines contains three integers s_{i}, m_{i}, r_{i} (0 ≤ s_{i} ≤ m_{i} ≤ 10^{5}; 0 ≤ r_{i} ≤ 10^{5}), describing a pony.
The next line contains an integer m (1 ≤ m ≤ 10^{5}) — the number of instructions. Each of the next m lines contains three integers t_{i}, l_{i}, r_{i} (0 ≤ t_{i} ≤ 10^{9}; 1 ≤ l_{i} ≤ r_{i} ≤ n), describing an instruction of Lord Tirek. The instructions are given in strictly increasing order of t_{i} (all t_{i} are distinct).
For each instruction, output a single line which contains a single integer, the total mana absorbed in this instruction.

Every pony starts with zero mana. For the first instruction, each pony has 5 mana, so you get 25 mana in total and each pony has 0 mana after the first instruction.
For the second instruction, pony 3 has 14 mana and other ponies have mana equal to their m_{i}.
