Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. We have N pieces of ropes, numbered 1 through N. The length of piece i is a_i. At first, for each i (1≤i≤N-1), piece i and piece i+1 are tied at the ends, forming one long rope with N-1 knots. Snuke will try to untie all of the knots by performing the following operation repeatedly: * Choose a (connected) rope with a total length of at least L, then untie one of its knots. Is it possible to untie all of the N-1 knots by properly applying this operation? If the answer is positive, find one possible order to untie the knots. Constraints * 2≤N≤10^5 * 1≤L≤10^9 * 1≤a_i≤10^9 * All input values are integers. Input The input is given from Standard Input in the following format: N L a_1 a_2 ... a_n Output If it is not possible to untie all of the N-1 knots, print `Impossible`. If it is possible to untie all of the knots, print `Possible`, then print another N-1 lines that describe a possible order to untie the knots. The j-th of those N-1 lines should contain the index of the knot that is untied in the j-th operation. Here, the index of the knot connecting piece i and piece i+1 is i. If there is more than one solution, output any. Examples Input 3 50 30 20 10 Output Possible 2 1 Input 2 21 10 10 Output Impossible Input 5 50 10 20 30 40 50 Output Possible 1 2 3 4 Submitted Solution: ``` n,l = map(int,input().split()) a = list(map(int,input().split())) memo = -1 for i in range(n-1): if a[i]+a[i+1] >= l: memo = i if memo == -1: print("Impossible") else: print("Possible") for i in range(n-1): if i != memo: print(i+1) print(memo+1) ```

Provide a correct Python 3 solution for this coding contest problem. We have N irregular jigsaw pieces. Each piece is composed of three rectangular parts of width 1 and various heights joined together. More specifically: * The i-th piece is a part of height H, with another part of height A_i joined to the left, and yet another part of height B_i joined to the right, as shown below. Here, the bottom sides of the left and right parts are respectively at C_i and D_i units length above the bottom side of the center part. <image> Snuke is arranging these pieces on a square table of side 10^{100}. Here, the following conditions must be held: * All pieces must be put on the table. * The entire bottom side of the center part of each piece must touch the front side of the table. * The entire bottom side of the non-center parts of each piece must either touch the front side of the table, or touch the top side of a part of some other piece. * The pieces must not be rotated or flipped.

Provide a correct Python 3 solution for this coding contest problem. We have N balance beams numbered 1 to N. The length of each beam is 1 meters. Snuke walks on Beam i at a speed of 1/A_i meters per second, and Ringo walks on Beam i at a speed of 1/B_i meters per second. Snuke and Ringo will play the following game: * First, Snuke connects the N beams in any order of his choice and makes a long beam of length N meters. * Then, Snuke starts at the left end of the long beam. At the same time, Ringo starts at a point chosen uniformly at random on the long beam. Both of them walk to the right end of the long beam. * Snuke wins if and only if he catches up to Ringo before Ringo reaches the right end of the long beam. That is, Snuke wins if there is a moment when Snuke and Ringo stand at the same position, and Ringo wins otherwise. Find the probability that Snuke wins when Snuke arranges the N beams so that the probability of his winning is maximized. This probability is a rational number, so we ask you to represent it as an irreducible fraction P/Q (to represent 0, use P=0, Q=1).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. We have N balance beams numbered 1 to N. The length of each beam is 1 meters. Snuke walks on Beam i at a speed of 1/A_i meters per second, and Ringo walks on Beam i at a speed of 1/B_i meters per second. Snuke and Ringo will play the following game: * First, Snuke connects the N beams in any order of his choice and makes a long beam of length N meters. * Then, Snuke starts at the left end of the long beam. At the same time, Ringo starts at a point chosen uniformly at random on the long beam. Both of them walk to the right end of the long beam. * Snuke wins if and only if he catches up to Ringo before Ringo reaches the right end of the long beam. That is, Snuke wins if there is a moment when Snuke and Ringo stand at the same position, and Ringo wins otherwise. Find the probability that Snuke wins when Snuke arranges the N beams so that the probability of his winning is maximized. This probability is a rational number, so we ask you to represent it as an irreducible fraction P/Q (to represent 0, use P=0, Q=1).

Provide a correct Python 3 solution for this coding contest problem. Snuke loves constructing integer sequences. There are N piles of stones, numbered 1 through N. The pile numbered i consists of a_i stones. Snuke will construct an integer sequence s of length Σa_i, as follows: 1. Among the piles with the largest number of stones remaining, let x be the index of the pile with the smallest index. Append x to the end of s. 2. Select a pile with one or more stones remaining, and remove a stone from that pile. 3. If there is a pile with one or more stones remaining, go back to step 1. Otherwise, terminate the process. We are interested in the lexicographically smallest sequence that can be constructed. For each of the integers 1,2,3,...,N, how many times does it occur in the lexicographically smallest sequence?

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Snuke loves constructing integer sequences. There are N piles of stones, numbered 1 through N. The pile numbered i consists of a_i stones. Snuke will construct an integer sequence s of length Σa_i, as follows: 1. Among the piles with the largest number of stones remaining, let x be the index of the pile with the smallest index. Append x to the end of s. 2. Select a pile with one or more stones remaining, and remove a stone from that pile. 3. If there is a pile with one or more stones remaining, go back to step 1. Otherwise, terminate the process.

If the i-th character of s is `1`, the i-th cell (from left) contains a token. Otherwise, it doesn't contain a token. Snuke wants to perform the following operation as many times as possible. In each operation, he chooses three consecutive cells. Let's call the cells X, Y, Z from left to right.
