Provide tags and a correct Python 3 solution for this coding contest problem. There are two types of burgers in your restaurant β€” hamburgers and chicken burgers! To assemble a hamburger you need two buns and a beef patty. To assemble a chicken burger you need two buns and a chicken cutlet. You have b buns, p beef patties and f chicken cutlets in your restaurant. You can sell one hamburger for h dollars and one chicken burger for c dollars. Calculate the maximum profit you can achieve. You have to answer t independent queries. Input The first line contains one integer t (1 ≀ t ≀ 100) – the number of queries. The first line of each query contains three integers b, p and f (1 ≀ b, ~p, ~f ≀ 100) β€” the number of buns, beef patties and chicken cutlets in your restaurant. The second line of each query contains two integers h and c (1 ≀ h, ~c ≀ 100) β€” the hamburger and chicken burger prices in your restaurant. Output For each query print one integer β€” the maximum profit you can achieve. Example Input 3 15 2 3 5 10 7 5 2 10 12 1 100 100 100 100 Output 40 34 0 Note In first query you have to sell two hamburgers and three chicken burgers. Your income is 2 β‹… 5 + 3 β‹… 10 = 40. In second query you have to ell one hamburgers and two chicken burgers. Your income is 1 β‹… 10 + 2 β‹… 12 = 34. In third query you can not create any type of burgers because because you have only one bun. So your income is zero.

The second line of each query contains two integers h and c (1 ≀ h, ~c ≀ 100) β€” the hamburger and chicken burger prices in your restaurant. Output For each query print one integer β€” the maximum profit you can achieve. Example Input 3 15 2 3 5 10 7 5 2 10 12 1 100 100 100 100 Output 40 34 0 Note In first query you have to sell two hamburgers and three chicken burgers. Your income is 2 β‹… 5 + 3 β‹… 10 = 40. In second query you have to ell one hamburgers and two chicken burgers. Your income is 1 β‹… 10 + 2 β‹… 12 = 34. In third query you can not create any type of burgers because because you have only one bun. So your income is zero.

Provide tags and a correct Python 3 solution for this coding contest problem. The only difference between easy and hard versions is constraints. The BerTV channel every day broadcasts one episode of one of the k TV shows. You know the schedule for the next n days: a sequence of integers a_1, a_2, ..., a_n (1 ≀ a_i ≀ k), where a_i is the show, the episode of which will be shown in i-th day. The subscription to the show is bought for the entire show (i.e. for all its episodes), for each show the subscription is bought separately. How many minimum subscriptions do you need to buy in order to have the opportunity to watch episodes of purchased shows d (1 ≀ d ≀ n) days in a row? In other words, you want to buy the minimum number of TV shows so that there is some segment of d consecutive days in which all episodes belong to the purchased shows. Input The first line contains an integer t (1 ≀ t ≀ 10000) β€” the number of test cases in the input. Then t test case descriptions follow. The first line of each test case contains three integers n, k and d (1 ≀ n ≀ 2β‹…10^5, 1 ≀ k ≀ 10^6, 1 ≀ d ≀ n). The second line contains n integers a_1, a_2, ..., a_n (1 ≀ a_i ≀ k), where a_i is the show that is broadcasted on the i-th day. It is guaranteed that the sum of the values ​​of n for all test cases in the input does not exceed 2β‹…10^5. Output Print t integers β€” the answers to the test cases in the input in the order they follow. The answer to a test case is the minimum number of TV shows for which you need to purchase a subscription so that you can watch episodes of the purchased TV shows on BerTV for d consecutive days. Please note that it is permissible that you will be able to watch more than d days in a row. Example Input 4 5 2 2 1 2 1 2 1 9 3 3 3 3 3 2 2 2 1 1 1 4 10 4 10 8 6 4 16 9 8 3 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 Output 2 1 4 5 Note In the first test case to have an opportunity to watch shows for two consecutive days, you need to buy a subscription on show 1 and on show 2. So the answer is two. In the second test case, you can buy a subscription to any show because for each show you can find a segment of three consecutive days, consisting only of episodes of this show. In the third test case in the unique segment of four days, you have four different shows, so you need to buy a subscription to all these four shows. In the fourth test case, you can buy subscriptions to shows 3,5,7,8,9, and you will be able to watch shows for the last eight days.

Example Input 4 5 2 2 1 2 1 2 1 9 3 3 3 3 3 2 2 2 1 1 1 4 10 4 10 8 6 4 16 9 8 3 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 Output 2 1 4 5 Note In the first test case to have an opportunity to watch shows for two consecutive days, you need to buy a subscription on show 1 and on show 2. So the answer is two. In the second test case, you can buy a subscription to any show because for each show you can find a segment of three consecutive days, consisting only of episodes of this show. In the third test case in the unique segment of four days, you have four different shows, so you need to buy a subscription to all these four shows. In the fourth test case, you can buy subscriptions to shows 3,5,7,8,9, and you will be able to watch shows for the last eight days.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. The only difference between easy and hard versions is constraints. The BerTV channel every day broadcasts one episode of one of the k TV shows. You know the schedule for the next n days: a sequence of integers a_1, a_2, ..., a_n (1 ≀ a_i ≀ k), where a_i is the show, the episode of which will be shown in i-th day. The subscription to the show is bought for the entire show (i.e. for all its episodes), for each show the subscription is bought separately. How many minimum subscriptions do you need to buy in order to have the opportunity to watch episodes of purchased shows d (1 ≀ d ≀ n) days in a row? In other words, you want to buy the minimum number of TV shows so that there is some segment of d consecutive days in which all episodes belong to the purchased shows. Input The first line contains an integer t (1 ≀ t ≀ 10000) β€” the number of test cases in the input. Then t test case descriptions follow. The first line of each test case contains three integers n, k and d (1 ≀ n ≀ 2β‹…10^5, 1 ≀ k ≀ 10^6, 1 ≀ d ≀ n). The second line contains n integers a_1, a_2, ..., a_n (1 ≀ a_i ≀ k), where a_i is the show that is broadcasted on the i-th day. It is guaranteed that the sum of the values ​​of n for all test cases in the input does not exceed 2β‹…10^5.

In other words, you want to buy the minimum number of TV shows so that there is some segment of d consecutive days in which all episodes belong to the purchased shows. Input The first line contains an integer t (1 ≀ t ≀ 10000) β€” the number of test cases in the input. Then t test case descriptions follow. The first line of each test case contains three integers n, k and d (1 ≀ n ≀ 2β‹…10^5, 1 ≀ k ≀ 10^6, 1 ≀ d ≀ n). The second line contains n integers a_1, a_2, ..., a_n (1 ≀ a_i ≀ k), where a_i is the show that is broadcasted on the i-th day. It is guaranteed that the sum of the values ​​of n for all test cases in the input does not exceed 2β‹…10^5. Output Print t integers β€” the answers to the test cases in the input in the order they follow. The answer to a test case is the minimum number of TV shows for which you need to purchase a subscription so that you can watch episodes of the purchased TV shows on BerTV for d consecutive days. Please note that it is permissible that you will be able to watch more than d days in a row. Example Input 4 5 2 2 1 2 1 2 1 9 3 3 3 3 3 2 2 2 1 1 1 4 10 4 10 8 6 4 16 9 8 3 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 Output 2 1 4 5 Note In the first test case to have an opportunity to watch shows for two consecutive days, you need to buy a subscription on show 1 and on show 2. So the answer is two. In the second test case, you can buy a subscription to any show because for each show you can find a segment of three consecutive days, consisting only of episodes of this show. In the third test case in the unique segment of four days, you have four different shows, so you need to buy a subscription to all these four shows. In the fourth test case, you can buy subscriptions to shows 3,5,7,8,9, and you will be able to watch shows for the last eight days.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Arkady and Masha want to choose decorations for thier aquarium in Fishdom game. They have n decorations to choose from, each of them has some cost. To complete a task Arkady and Masha need to choose exactly m decorations from given, and they want to spend as little money as possible. There is one difficulty: Masha likes some a of the given decorations, Arkady likes some b of the given decorations. Some decorations may be liked by both Arkady and Masha, or not be liked by both. The friends want to choose such decorations so that each of them likes at least k decorations among the chosen. Help Masha and Arkady find the minimum sum of money they need to spend. Input The first line contains three integers n, m and k (1 ≀ n ≀ 200000, 1 ≀ m ≀ n, 1 ≀ k ≀ n) β€” the number of decorations, how many decorations the friends should choose, how many decorations each of them should like among the chosen. The second line contains n integers c1, c2, ..., cn (1 ≀ ci ≀ 109) β€” decorations costs. The third line contains single integer a (1 ≀ a ≀ n) β€” the number of decorations liked by Masha. The fourth line contains a distinct integers x1, x2, ..., xa (1 ≀ xi ≀ n) β€” the ids of decorations liked by Masha. The next two lines describe decorations liked by Arkady in the same format.

Provide a correct Python 3 solution for this coding contest problem. There is a long-established secondhand bookstore called JOI secondhand bookstore in your town, and you often use the JOI secondhand bookstore. Each book has a standard price, and you can buy it at that price if you go to the JOI secondhand bookstore. At the JOI secondhand bookstore, books are classified into 10 genres such as novels, manga, and magazines. Genres are numbered from 1 to 10. The JOI secondhand bookstore has a service that if you buy books of the same genre in bulk, they will buy them at a high price. Specifically, when books of the same genre are purchased together in T books, the purchase price per book of that genre is T -1 yen higher than the standard price. For example, if books of the same genre with standard prices of 100 yen, 120 yen, and 150 yen are sold together at the JOI secondhand bookstore, the purchase prices will be 102 yen, 122 yen, and 152 yen, respectively.
