Problem Description

The picture indicates a tree, every node has 2 children.
The depth of the nodes whose color is blue is 3; the depth of the node whose color is pink is 0.
Now out problem is so easy, give you a tree that every nodes have K children, you are expected to calculate the minimize depth D so that the number of nodes whose depth is D equals to N after mod P.

Input
The input consists of several test cases.
Every cases have only three integers indicating K, P, N. (1<=K, P, N<=10^9)

Output
The minimize D.
If you can’t find such D, just output “Orz,I can’t find D!”

Sample Input
3 78992 453
4 1314520 65536
5 1234 67

Sample Output
Orz,I can’t find D!

c# 关于构建表达式树的问题
Expression<Action<object, object[]>> ex = (ins, param) => ((Program)ins).Call(param[0], param[1], param[2]); 有以上表达式，如何构建该表达式树？ 通过Expression Tree Visualizer看到表达式结构是这样的![图片说明](https://img-ask.csdn.net/upload/201607/10/1468120211_837373.png)但不知道如何构建表达式树，希望高手能指导一下，我自己构建了一段：ParameterExpression px = Expression.Parameter(typeof(object[]), "argus"); ConstantExpression index1 = Expression.Constant(0); ConstantExpression index2 = Expression.Constant(1); ConstantExpression index3 = Expression.Constant(1); BinaryExpression pm1 = Expression.ArrayIndex(px, index1); BinaryExpression pm2 = Expression.ArrayIndex(px, index2); BinaryExpression pm3 = Expression.ArrayIndex(px, index3); 后面构建主体的时候就不太清楚了，谢谢赐教

Problem Description Brian's little sister Mary is fond of strange games involving lots of calculation. Unfortunately she's not so good at mathematics so Brian's often asked to calculate the values needed for her. Recently Brian's facing another such problem: An undirected graph with N vertexes and M edges is first drawn by Mary. Then, Mary randomly assigns an integer value to each of the vertexes. After that, Mary will perform a sequence of operations on the graph, each operation being of one of the following type: a) Among all vertexes connecting with vertex X via some edges, find the least value that is no less than value K. If such value cannot be found, zero will be returned instead. b) Updates the value assigned to vertex X to K. c) Erases an edge connecting vertex A and B from the graph. Mary’s interested in the average value of all answers to type a) operations. Would you please help Brian to finish this boring task? Input There are multiple test cases in the input file. Each case starts with three integers, N, M, and Q (1 <= N <= 2 * 104, 0 <= M <= 6 * 104, 1 <= Q <= 3 * 105). The next N lines describe the initial value assigned to each vertex. The next part of each test case consists of M lines, and describes the edges in the graph at the beginning. Vertexes are numbered from 1 to N. The last part of each test case describes the operations to be performed on the tree. For operations of a) type, a line similar to “F X K” will be given; for operations of b) type, a line with the format of “U X K” will be given; and for c) type, the description will be given in the format similar to “E A B”. You can assume that there will always be at least one a) type query. The absolute value assigned to any vertex at any time will not exceed 10000. There is a blank line between two successive cases. Input ends with End-of-File. Output For each test case, output one real number – the requested value with precision up to 0.001, in the format as indicated in the sample output. Sample Input 3 3 8 4 5 8 1 2 2 3 1 3 F 1 4 E 1 3 F 2 7 E 2 3 E 1 2 F 2 7 U 3 6 F 3 3 1 0 1 0 F 1 0 Sample Output Case 1: 4.500 Case 2: 0.000

C语言构建多文件程序，命令行
_大多数_编译器允许一步构建程序，例如，对于GCC来说，可以使用下列命令行来构建justify程序： gcc -o justify justify .c line.c word.c 这个命令行，我从一开始就没看懂，是跳过去学的后面。现在又在后面的章节中反复出现。请问，这些是需要手动输入吗？在哪里输入？写源程序的时候输入？还是运行了exe之后的黑框里输入？如果是后者的话，我的程序怎么分辨它是命令行还是程序内的输入（例如：假设我的程序有对scanf()的调用的话）？

A tempting approach to maintaining a balanced binary search tree is to maintain two binary search trees and to insert each new key into the tree that will be more balanced. More specifically, do the following: The first key is the root of the left tree. The second key is the root of the right tree. To add a new key, insert it into the tree where it would have a smaller depth. If the depths of both trees are the same, then add it to the first tree.The input will be 5 strings (ignore everything but the letters A through Z and a through z; uppercase and lowercase are the same). For each input string, build the two trees with each string as described above. Print contents of the first tree in preorder (root, then the left child, then the right child). Sample Input: Line #1: AMERICAN COMPUTER SCIENCE Line #2: I must say that I find television very educational Line #3: INTERMEDIATE DIVISION Sample Output: Output #1: A A E C C E E N I P S Output #2: I A A A A I D D C E E I U T T S R U Y V Y Output #3: I E E A I I I T T V 维护一个平衡的二叉搜索树的一个诱人的方法是维护两个二叉搜索树，并将每个新键插入树中，这样会更加平衡。更具体地说，执行以下操作:第一个键是左树的根。第二个键是右树的根。若要添加新键，请将其插入到树中其深度较小的位置。如果两棵树的深度相同，则将其添加到第一棵树上。 输入将是5个字符串(忽略除了字母A到Z和A到Z;大写和小写是一样的)。对于每个输入字符串，使用上面描述的每个字符串构建两个树。按顺序打印第一个树的内容(根，然后左子树，然后右子树)。 样例输入: 第一行:美国计算机科学 我得说我觉得电视很有教育意义 第3行:中间部分 样例输出: 输出#1:A A E C C E E N I P S 输出#2:I A A A I D D C E E I U T S R U Y V Y 输出#3:ieia I I T T V 基本要求:算法合理，结果准确

C语言如何用for循环构建2*2矩阵
2*2矩阵： 1 2 3 4 很简单的矩阵 不过不用scanf输入 直接用for循环输出 我想的方法是定义一个变量x=1，然后在for循环里面，每一次x++存入数组 代码： ``` #include<stdio.h> int main() { int a[2][2]; int i,j,x=1; for(i=0;i<2;i++) for(j=0;j<2;j++) { a[i][j]=x; x++; } printf("%d\n",a[i][j]); return 0; } ``` 输出结果只有1，实在不解
