P1: 进制转化Time Limit: 1000MS Memory Limit: 16000KDescription输入一个十进制数，转化成十六进制数，然后输出。Input含有多组测试数据，每组测试数据仅一个正整数N(N109)，表示十进制数，读文件结束。Output对每个测试用例，输出N对应的十六进制数。Sample Input1125Sample OutputB19P2: 硬币问题Time Limit: 1000MS Memory Limit: 16000KDescription小明有n(n=30)枚硬币,每一枚硬币的面值不等。小明现在想要用这些硬币拼出一个最大的价值M，且1到M之间所有的数都能用这些硬币拼出来，对于组一个数，每一枚硬币只能用一次，不能多次使用。现在小明需要你帮他确定这个最大价值M，以及每枚硬币的面值。例如n=2时，最大价值为3，两枚硬币分别为1,2，这样1由1组成，2由2组成，3由1和2组成。Input含有多组测试数据，每组测试数据仅一个正整数n,读文件结束。Output对每个测试用例，输出两行。第一行输出M。第二行输出每一枚硬币的面值，从小到大排序，每个面值中间用空格隔开。Sample Input2Sample Output31 2P3: Bone CollectorTime Limit: 1000MS Memory Limit: 16000KDescriptionMany years ago , in Teddys hometown there was a man who was called “Bone Collector”. This man like to collect varies of bones , such as dogs , cows , also he went to the grave The bone collector had a big bag with a volume of V ,and along his trip of collecting there are a lot of bones , obviously , different bone has different value and different volume, now given the each bones value along his trip , can you calculate out the maximum of the total value the bone collector can get ?InputThe first line contain a integer T , the number of cases.Followed by T cases , each case three lines , the first line contain two integer N , V, (N = 1000 , V = 1000 )representing the number of bones and the volume of his bag. And the second line contain N integers representing the value of each bone. The third line contain N integers representing the volume of each bone.OutputOne integer per line representing the maximum of the total value (this number will be less than 231).Sample Input15 101 2 3 4 55 4 3 2 1Sample Output14P4: 母猪的故事Time Limit: 1000MS Memory Limit: 16000KDescription话说现在猪肉价格这么贵，著名的ACBoy 0068 也开始了养猪生活。说来也奇怪，他养的猪一出生第二天开始就能每天中午生一只小猪，而且生下来的竟然都是母猪。不过光生小猪也不行，0068采用了一个很奇特的办法来管理他的养猪场：对于每头刚出生的小猪，在他生下第二头小猪后立马被杀掉，卖到超市里。假设在创业的第一天，0068只买了一头刚出生的小猪，请问，在第N天晚上，0068的养猪场里还存有多少头猪？Input测试数据的第一行包含有一个正整数T，代表测试数据的个数。接下来有T组测试，每组测试数据占一行，分别有一个正整数N代表0068创业的第N天。(0N20)。Output对于每组数据，请在一行里输出第N天晚上养猪场里猪的数目。Sample Input232Sample Output23P5: Oil DepositsTime Limit: 1000MS Memory Limit: 16000KDescriptionThe GeoSurvComp geologic survey company is responsible for detecting underground oil deposits. GeoSurvComp works with one large rectangular region of land at a time, and creates a grid that divides the land into numerous square plots. It then analyzes each plot separately, using sensing equipment to determine whether or not the plot contains oil. A plot containing oil is called a pocket. If two pockets are adjacent, then they are part of the same oil deposit. Oil deposits can be quite large and may contain numerous pockets. Your job is to determine how many different oil deposits are contained in a grid. InputThe input file contains one or more grids. Each grid begins with a line containing m and n, the number of rows and columns in the grid, separated by a single space. If m = 0 it signals the end of the input; otherwise 1 = m = 100 and 1 = n = 100. Following this are m lines of n characters each (not counting the end-of-line characters). Each character corresponds to one plot, and is either *, representing the absence of oil, or , representing an oil pocket.OutputFor each grid, output the number of distinct oil deposits. Two different pockets are part of the same oil deposit if they are adjacent horizontally, vertically, or diagonally. An oil deposit will not contain more than 100 pockets.Sample Input1 1*3 5*1 8*0 0Sample Output012P6: The kth great numberTime Limit: 1000MS Memory Limit: 16000KDescriptionXiao Ming and Xiao Bao are playing a simple Numbers game.In a round Xiao Ming can choose to write down a number, or ask Xiao Bao what the kth great number is. Because the number written by Xiao Ming is too much, Xiao Bao is feeling giddy. Now, try to help Xiao Bao.InputThere are several test cases. For each test case, the first line of input contains two positive integer n, k. Then n lines follow. If Xiao Ming choose to write down a number, there will be an I followed by a number that Xiao Ming will write down. If Xiao Ming choose to ask Xiao Bao, there will be a Q, then you need to output the kth great number. OutputThe output consists of one integer representing the largest number of islands that all lie on one line.
