Niwango-kun is an employee of Dwango Co., Ltd.
One day, he is asked to generate a thumbnail from a video a user submitted.
To generate a thumbnail, he needs to select a frame of the video according to the following procedure:
* Get an integer N and N integers a_0, a_1, ..., a_{N-1} as inputs. N denotes the number of the frames of the video, and each a_i denotes the representation of the i-th frame of the video.
* Select t-th frame whose representation a_t is nearest to the average of all frame representations.
* If there are multiple such frames, select the frame with the smallest index.
Find the index t of the frame he should select to generate a thumbnail.

Dr. Evil is interested in math and functions, so he gave Mahmoud and Ehab array a of length n and array b of length m. He introduced a function f(j) which is defined for integers j, which satisfy 0 ≤ j ≤ m - n. Suppose, ci = ai - bi + j. Then f(j) = |c1 - c2 + c3 - c4... cn|. More formally, <image>.
Dr. Evil wants Mahmoud and Ehab to calculate the minimum value of this function over all valid j. They found it a bit easy, so Dr. Evil made their task harder. He will give them q update queries. During each update they should add an integer xi to all elements in a in range [li;ri] i.e. they should add xi to ali, ali + 1, ... , ari and then they should calculate the minimum value of f(j) for all valid j.
Please help Mahmoud and Ehab.
Input
The first line contains three integers n, m and q (1 ≤ n ≤ m ≤ 105, 1 ≤ q ≤ 105) — number of elements in a, number of elements in b and number of queries, respectively.
The second line contains n integers a1, a2, ..., an. ( - 109 ≤ ai ≤ 109) — elements of a.
The third line contains m integers b1, b2, ..., bm. ( - 109 ≤ bi ≤ 109) — elements of b.
Then q lines follow describing the queries. Each of them contains three integers li ri xi (1 ≤ li ≤ ri ≤ n, - 109 ≤ x ≤ 109) — range to be updated and added value.
Output
The first line should contain the minimum value of the function f before any update.
Then output q lines, the i-th of them should contain the minimum value of the function f after performing the i-th update .

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
You are given an array of n integer numbers a0, a1, ..., an - 1. Find the distance between two closest (nearest) minimums in it. It is guaranteed that in the array a minimum occurs at least two times.
Input
The first line contains positive integer n (2 ≤ n ≤ 105) — size of the given array. The second line contains n integers a0, a1, ..., an - 1 (1 ≤ ai ≤ 109) — elements of the array. It is guaranteed that in the array a minimum occurs at least two times.
Output
Print the only number — distance between two nearest minimums in the array.
