Takahashi and Aoki will have a battle using their monsters.

those of Aoki's monster are C and D, respectively.

Takahashi's, Aoki's, ... Here, an attack decreases the opponent's health by
the value equal to the attacker's strength. The monsters keep attacking until
the health of one monster becomes 0 or below. The person with the monster
whose health becomes 0 or below loses, and the other person wins.

| Switching Railroad Cars
This figure shows railway tracks for reshuffling cars. The rail tracks end in
the bottom and the top-left rail track is used for the entrace and the top-
right rail track is used for the exit. Ten cars, which have numbers from 1 to
10 respectively, use the rail tracks.
We can simulate the movement (comings and goings) of the cars as follow:
* An entry of a car is represented by its number.
* An exit of a car is represented by 0
For example, a sequence
1
6
0
8
10
demonstrates that car 1 and car 6 enter to the rail tracks in this order, car
6 exits from the rail tracks, and then car 8 and car 10 enter.
Write a program which simulates comings and goings of the cars which are
represented by the sequence of car numbers. The program should read the
sequence of car numbers and 0, and print numbers of cars which exit from the
rail tracks in order. At the first, there are no cars on the rail tracks. You
can assume that 0 will not be given when there is no car on the rail tracks. | [{"input": "6\n 0\n 8\n 10\n 0\n 0\n 0", "output": "10\n 8\n 1"}] |

Snuke got a present from his mother on his birthday. The present was a pair of
two sequences a and b, consisting of positive integers. They satisfied all of
the following properties:
* The sum of all elements of a is N.
* The sum of all elements of b is N.
* Any string of length N that satisfies the following two conditions (1) and (2) will also satisfy the condition (3).
* **(1)** Any of the following forms a palindrome: the first a_1 letters, the following a_2 letters, the following a_3 letters and so on.
* **(2)** Any of the following forms a palindrome: the first b_1 letters, the following b_2 letters, the following b_3 letters and so on.
* **(3)** All N letters are the same.
He was happy, until one day he lost both of the sequences. Now, he only
remembers that the sequence a was a permutation of another sequence A of
length M.
To bring him happiness again, his mother has decided to give him another pair
of sequences a and b that satisfies his favorite properties and is consistent
with his memory. | [{"input": "3 2\n 2 1", "output": "1 2\n 1\n 3\n \n\n* * *"}, {"input": "6 1\n 6", "output": "6\n 3\n 1 2 3\n \n\n* * *"}, {"input": "55 10\n 1 2 3 4 5 6 7 8 9 10", "output": "Impossible"}] |

We have N points numbered 1 to N arranged in a line in this order.
Takahashi decides to make an undirected graph, using these points as the
vertices. In the beginning, the graph has no edge. Takahashi will do M
operations to add edges in this graph. The i-th operation is as follows:
* The operation uses integers L_i and R_i between 1 and N (inclusive), and a positive integer C_i. For every pair of integers (s, t) such that L_i \leq s < t \leq R_i, add an edge of length C_i between Vertex s and Vertex t.
The integers L_1, ..., L_M, R_1, ..., R_M, C_1, ..., C_M are all given as
input.

obtained. Find the length of the shortest path from Vertex 1 to Vertex N in
the final graph. | [{"input": "4 3\n 1 3 2\n 2 4 3\n 1 4 6", "output": "5\n \n\nWe have an edge of length 2 between Vertex 1 and Vertex 2, and an edge of\nlength 3 between Vertex 2 and Vertex 4, so there is a path of length 5 between\nVertex 1 and Vertex 4.\n\n* * *"}, {"input": "4 2\n 1 2 1\n 3 4 2", "output": "-1\n \n\n* * *"}, {"input": "10 7\n 1 5 18\n 3 4 8\n 1 3 5\n 4 7 10\n 5 9 8\n 6 10 5\n 8 10 3", "output": "28"}] |
