Divan and a Cottage

题意翻译

给你间房子，将房子内的温度称为 $P$，将房子外的温度称为 $T$，其中， $P$ 受制于 $T$。 若前一天的`室温`为 $P$，`气温` 为 $T$，今天的`室温`为 $P_{new}$。 - $ P_{new} = P + 1 $ , if $ P < T $ , - $ P_{new} = P - 1 $ , if $ P > T $ , - $ P_{new} = P $ , if $ P = T $ . 然后依次给你 $n$ 天的 $T$，每天有 $k$ 个询问，询问：若第一天屋内`室温` 为 $x$，则到今天，`室温` $P$ 将会是多少？ 题目强制在线。

题目描述

Divan's new cottage is finally complete! However, after a thorough inspection, it turned out that the workers had installed the insulation incorrectly, and now the temperature in the house directly depends on the temperature outside. More precisely, if the temperature in the house is $ P $ in the morning, and the street temperature is $ T $ , then by the next morning the temperature in the house changes according to the following rule: - $ P_{new} = P + 1 $ , if $ P < T $ , - $ P_{new} = P - 1 $ , if $ P > T $ , - $ P_{new} = P $ , if $ P = T $ . Here $ P_{new} $ is the temperature in the house next morning.Divan is a very busy businessman, so sometimes he is not at home for long periods and does not know what the temperature is there now, so he hired you to find it. You will work for $ n $ days. In the beginning of the $ i $ -th day, the temperature outside $ T_i $ is first given to you. After that, on the $ i $ -th day, you will receive $ k_i $ queries. Each query asks the following: "if the temperature in the house was $ x_i $ at the morning of the first day, what would be the temperature in the house next morning (after day $ i $ )?" Please answer all the businessman's queries.

The first line of the input contains the number $ n $ ( $ 1 \leq n \leq 2 \cdot 10^5 $ ) — the number of days. The following is a description of $ n $ days in the following format. The first line of the description contains an integer $ T_i $ ( $ 0 \leq T_i \leq 10^9 $ ) — the temperature on that day. The second line contains a non-negative integer $ k_i $ ( $ 0 \le k_i \le 2 \cdot 10^5 $ ) — the number of queries that day. The third line contains $ k $ integers $ x'_i $ ( $ 0 \leq x'_{i} \leq 10^9 $ ) — the encrypted version of Divan's queries. Let $ lastans = 0 $ initially. Divan's actual queries are given by $ x_i = (x'_i + lastans) \bmod (10^9 + 1) $ , where $ a \bmod b $ is the reminder when $ a $ is divided by $ b $ . After answering the query, set $ lastans $ to the answer. It is guaranteed that the total number of queries (the sum of all $ k_i $ ) does not exceed $ 2 \cdot 10^5 $ .

输出格式

For each query, output a single integer — the temperature in the house after day $ i $ .

说明

Let's look at the first four queries from the example input. The temperature is $ 50 $ on the first day, $ 50 $ on the second day, and $ 0 $ on the third day. Note that $ lastans = 0 $ initially. - The initial temperature of the first query of the first day is $ (1 \, + \, lastans) \bmod (10^9 + 1) = 1 $ . After the first day, the temperature rises by $ 1 $ , because $ 1 < 50 $ . So the answer to the query is $ 2 $ . Then, we set $ lastans = 2 $ . - The initial temperature of the second query of the first day is $ (2 \, + \, lastans) \bmod (10^9 + 1) = 4 $ . After the first day, the temperature rises by $ 1 $ , because $ 4 < 50 $ . So the answer to the query is $ 5 $ . Then, we set $ lastans = 5 $ . - The initial temperature of the third query of the first day is $ (3 \, + \, lastans) \bmod (10^9 + 1) = 8 $ . After the first day, the temperature rises by $ 1 $ . So the answer to the query is $ 9 $ . Then, we set $ lastans = 9 $ . - The initial temperature of the first query of the second day is $ (4 \, + \, lastans) \bmod (10^9 + 1) = 13 $ . After the first day, the temperature rises by $ 1 $ . After the second day, the temperature rises by $ 1 $ . So the answer to the query is $ 15 $ . Then, we set $ lastans = 15 $ .
