Provide a correct Python 3 solution for this coding contest problem. Your friend gave you a dequeue D as a birthday present. D is a horizontal cylinder that contains a row of N jewels. The values of the jewels are V_1, V_2, ..., V_N from left to right. There may be jewels with negative values. In the beginning, you have no jewel in your hands. You can perform at most K operations on D, chosen from the following, at most K times (possibly zero): * Operation A: Take out the leftmost jewel contained in D and have it in your hand. You cannot do this operation when D is empty. * Operation B: Take out the rightmost jewel contained in D and have it in your hand. You cannot do this operation when D is empty. * Operation C: Choose a jewel in your hands and insert it to the left end of D. You cannot do this operation when you have no jewel in your hand. * Operation D: Choose a jewel in your hands and insert it to the right end of D. You cannot do this operation when you have no jewel in your hand. Find the maximum possible sum of the values of jewels in your hands after the operations. Constraints * All values in input are integers. * 1 \leq N \leq 50 * 1 \leq K \leq 100 * -10^7 \leq V_i \leq 10^7 Input Input is given from Standard Input in the following format: N K V_1 V_2 ...

D is a horizontal cylinder that contains a row of N jewels. The values of the jewels are V_1, V_2, ..., V_N from left to right. There may be jewels with negative values. In the beginning, you have no jewel in your hands. You can perform at most K operations on D, chosen from the following, at most K times (possibly zero): * Operation A: Take out the leftmost jewel contained in D and have it in your hand. You cannot do this operation when D is empty. * Operation B: Take out the rightmost jewel contained in D and have it in your hand. You cannot do this operation when D is empty. * Operation C: Choose a jewel in your hands and insert it to the left end of D. You cannot do this operation when you have no jewel in your hand. * Operation D: Choose a jewel in your hands and insert it to the right end of D. You cannot do this operation when you have no jewel in your hand. Find the maximum possible sum of the values of jewels in your hands after the operations.

Determine whether the magic can be successful. Constraints * 1 \leq A, B, C \leq 7 * 1 \leq K \leq 7 * All values in input are integers. Input Input is given from Standard Input in the following format: A B C K Output If the magic can be successful, print `Yes`; otherwise, print `No`. Examples Input 7 2 5 3 Output Yes Input 7 4 2 3 Output No Submitted Solution: ``` R,G,B = map(int,input().split()) K = int(input()) for i in range(K): if G < R: G *= 2 elif B <= G: B *= 2 # print('Green: ' + str(G) + ' blue:' + str(B)) if R < G and G < B: print('Yes') else: print('No') ```

Provide a correct Python 3 solution for this coding contest problem. Let's play the game using a bag containing several cards with integers written on it. In each game, participants first declare one of their favorite number n. Then, take out an appropriate number of cards from the bag at a time, and if the sum of the numbers written on those cards is equal to n, you will receive a luxurious prize. After each game, the cards will be returned to the bag. Create a program that inputs the information of m types of cards in the bag and the number declared by the participants in g games, and outputs how many combinations of cards can receive luxury products in each game. please. Input A sequence of multiple datasets is given as input. The end of the input is indicated by a single line of zeros. Each dataset is given in the following format: m a1 b1 a2 b2 :: am bm g n1 n2 :: ng The number of card types m (1 ≤ m ≤ 7) on the first line, the integer ai (1 ≤ ai ≤ 100) written on the i-type card on the following m line, and the number bi (1 ≤ bi ≤ 10) Are given with a space delimiter.
