題目描述

There is a new revolution in the parking lot business: the parking ?building. The concept is simple: you drive your car into the elevator at the entrance of the building, and the elevator and conveyor belts drag the car to an empty parking spot, where the car remains until you pick it up. When you return, the elevator and conveyor belts move your car back to the entrance and you’re done.
The layout of the building is simple. There is one central elevator that transports the cars between the different floors. On each floor there is one giant circular conveyor belt on which the cars stand. This belt can move in clockwise and counterclockwise direction. When the elevator arrives on a floor, it becomes part of the belt so that cars can move through it.
At the end of the day the building is usually packed with cars and a lot of people come to pick them up. Customers are processed in a first come first serve order: the elevator is moved to the floor of the first car, the conveyor belt moves the car on the elevator, the elevator is moved down again, and so on. We like to know how long it takes before the last customer gets his car. Moving the elevator one floor up- or downwards takes 10 seconds and moving ?the conveyor belt one position in either direction takes 5 seconds.?

輸入

On the first line one positive number: the number of testcases, at most 30. ?Each test case specifies:
?One line with two integers h and l with 1 ≤ h ≤ 50 and 2 ≤ l ≤ 50: the height of the parking tower and the length of the conveyor belts.
?h lines with l integers: the initial placement of the cars. The jth number on the ith line describes the jth position on the ith floor. This number is ?1 if the position is empty, and r if the position is occupied by the rth car to pick up. The positive numbers form a consecutive sequence from 1 to the number of cars. The entrance is on the first floor and the elevator (which is initially empty) is in the first position. There is at least one car in the parking tower.

輸出

For each test case generate a single line containing a single integer ?that is the number of seconds before the last customer is served.

題目描述

抗日戰爭時期,在國共合作的大背景下，中共不斷發展壯大，其情報工作也開始由獲取警報性、保衛性信息，向獲取軍政戰略性情報轉變。各系統情報組織遵循"蔭蔽精干,長期埋伏,積蓄力量,以待時機"的隱蔽戰線工作方針,開展了卓有成效的情報工作。
***特科組是中共情報工作的一個杰出范例,它以點為主、系統延伸、分散輻射的力量格局,異地領導、分頭派遣、單線聯系的組織形式。以打入、拉出、統戰聯絡、內線為主的工作方式,形成了一個傳遞信息隱蔽、效用及時、形式多樣的情報網絡。
***特科組的情報人員共有N人，其代號分別為0,1，……,N-1。 0號是最高領導人，特工之間有一套嚴格的單線聯絡程序，即，每個特工人員只有一個上線，他獲得的情報需層層上傳遞到0號手里，由0號發報出去。
特工i在傳遞情報時，若通往到0號的通道尚未建立，則需要建立一級級單線通道;若他的上線已建立好通道，只需建立兩人通道，信息發送給上線；依次類推。若特工i已建立好到0號的通道，則直接發出情報。日偽統治中心南京，既是情報來源豐富的地方，又是特工人員活動最危險的地方。因此，一旦某個特工處于不安全狀態，他必須馬上撤離，同時他的所有下線（處在通道上的一級級下線）也一同撤離。
已知***特科組的組織結構，你的任務是計算，當某特工i需要發送情報時，最少需要建立幾個情報人員的通道；當某特工i處于不安全狀態時，最少需要撤離多少人員。

輸入

第一行一個整數： ?N ? ? ? ? ? （ 1≤N ≤5060 ）
接下來一行有N-1 個整數， ?A1 A2 ……An-1 ?，其中Ai是編號i的上線。
下一行一個整數： ?M ? ? ? ? 表示有M個狀態，（ 1≤M ≤5060 ）
接下來有M行 ：有兩種形式： ?Send i ? ?特工i處于要發送情報狀態；
? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Danger i ?特工i處于不安全狀態

輸出

輸出占M行 ，對于Send i，輸出最少需要建立通道的情報人員數，若特工i處于通道線上，輸出0；對于Danger i，輸出最少需要撤離多少人員，若特工i不處于通道線上，則輸出0.

題目描述

To facilitate the analysis of ?a DNA sequence, ?a DNA sequence is represented by a binary ?number. The group of ?DNA-1 has discovered a great new way . ?There is a certain correlation between binary number and prime number. Instead of using the ordinary decadic numbers, they use prime base numbers. Numbers in this base are expressed as sequences of zeros and ones similarly to the binary numbers, but the weights of bits ?in the representation are not powers of two, but the elements of the primes ?( 2, 3, 5, 7,... ).?

For example ?01101 , ie. 2+5+7=14?

Herefore, it is necessary to convert the binary number to the sum of prime numbers。

There is a mysterious lake in the north of Tibet. As the sun shines, the surface of the lake is colorful and colorful. The lake was unfathomable in rainy weather. ?After the probe, ?It has an interesting bottom in that it is full of little hills and valleys. . Scientists wonders how deep the bottom of the lake is.

Scientists use the most advanced radar equipment to detect the bottom of the lake. It is the discovery that the deepest part is relatively flat. Thet want to know the largest depth number only if it is verified by the fact that the same depth appears in an adjacent reading.

To facilitate computing, scientists have put the lake as M * N grids . The depth ?reading of each grid is already known. some readings might be 0-- It's a small island on the lake.
?
Find the greatest depth that appears in at least two 'adjacent'readings (where 'adjacent' means in any of the potentially eight squares that border a square on each of its sides and its diagonals). The lake has at least one pair of positive, adjacent readings.

輸入

The first line of the input contains one integers T, which is the nember of ?test cases (1<=T<=5). ?Each test case specifies:

* Line 1: Two space-separated integers: M and N ? (1 ≤ M, ?N ≤ 50)
* Lines 2..M+1: Line i+1 contains N space-separated integers that ?represent the depth of the lake across row i: Dij ? ?(0 <= Dij <=1,000,000);

輸出

For each test case generate a single line: ?a single integer that is the depth of the lake determined.
