hdu 5237 二进制

很无聊的模拟题。。。mark几个有用的小程序：

字符->二进制ASCII码

 1 string tobin(char c)
 2 {
 3     string t;
 4     for(int i=0; i<8; i++)
 5     {
 6         t=char(c%2+48)+t;
 7         c/=2;
 8     }
 9     return t;
10 }

hdu 3584 二进制0,1反转三维树状数组及三维树状数组模板

先贴自己类比二维树状数组写的三维树状数组模板: 开始的时候循环体内j=y,k=z,没写,以为自己思路错了,,,hehe..... 更高维的树状数组以此类比 const int MAXN = 100+10; int c[MAXN][MAXN][MAXN];int X,Y,Z; int N; inline int lowbit(int x){return x&(-x);} void update(int x, int y, int z, int v) { int i=x,j=y,k=z; while

HDU 6166 二进制划分集合

首先这个题化成两个集合还是很容易的想到的,但是不知道怎么用二进制表示,感觉这个题的脑洞还是很大的. 为什么可以用二进制表示化成集合可以包含所有的点对,因为要是两个数不同的话肯定会有一个二进制的位数不同所以就包含了所有的点对. #include<stdio.h> #include<string.h> #include<algorithm> #include<queue> using namespace std; const int N=5e5; struct
