The Cartesian coordinate system is set in the sky. There you can see n stars, the i-th has coordinates (xiyi), a maximum brightness c, equal for all stars, and an initial brightness si (0 ≤ si ≤ c).

Over time the stars twinkle. At moment 0 the i-th star has brightness si. Let at moment t some star has brightness x. Then at moment (t + 1) this star will have brightness x + 1, if x + 1 ≤ c, and 0, otherwise.

You want to look at the sky q times. In the i-th time you will look at the moment ti and you will see a rectangle with sides parallel to the coordinate axes, the lower left corner has coordinates (x1iy1i) and the upper right — (x2iy2i). For each view, you want to know the total brightness of the stars lying in the viewed rectangle.

A star lies in a rectangle if it lies on its border or lies strictly inside it.

Input

The first line contains three integers nqc (1 ≤ n, q ≤ 1051 ≤ c ≤ 10) — the number of the stars, the number of the views and the maximum brightness of the stars.

The next n lines contain the stars description. The i-th from these lines contains three integers xiyisi (1 ≤ xi, yi ≤ 1000 ≤ si ≤ c ≤ 10) — the coordinates of i-th star and its initial brightness.

The next q lines contain the views description. The i-th from these lines contains five integers tix1iy1ix2iy2i (0 ≤ ti ≤ 1091 ≤ x1i < x2i ≤ 1001 ≤ y1i < y2i ≤ 100) — the moment of the i-th view and the coordinates of the viewed rectangle.

Output

For each view print the total brightness of the viewed stars.

Note

Let's consider the first example.

At the first view, you can see only the first star. At moment 2 its brightness is 3, so the answer is 3.

At the second view, you can see only the second star. At moment 0 its brightness is 0, so the answer is 0.

At the third view, you can see both stars. At moment 5 brightness of the first is 2, and brightness of the second is 1, so the answer is 3.

题目的意思有一片100*100的星空,上面有n颗星星,每个星星有一个亮度,且在

0~C范围内周期性变化,现在给出q个查询,每个查询给出时间和一个矩形,求在该

时间时矩形内星星的亮度和。

思路:先预处理处每个区域每种亮度的星星有多少颗,可以直接搞波前缀和,然后

枚举各个亮度在查询区域内的星星个数,计算总和
