Description There is a special number sequence which has n+1 integers. For each number in sequence, we have two rules: ● a i ∈ [0,n] ● a i ≠ a j( i ≠ j ) For sequence a and sequence b, the integrating degree t is defined as follows(“�” denotes exclus…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5014 解题报告:西安网赛的题,当时想到一半,只想到从大的开始匹配,做异或运算得到对应的b[i],但是少了一个操作,ans[i] = temp,却没有想到ans[temp] = i;所以就一直卡在这里了,因为我不确定这样是不是一一对应的,好吧,也没有想到这里,就差这么点了. #include<cstdio> #include<cstring> #include<iostream&g…

为了a异或b的和最大,只需另b在不大于n的情况下按位取反即可. 这里有两个输出小技巧可以参考: 1.在用printf输出__int64时,在windows下使用格式"%I64d",在linux下使用"%lld",在hdu中应使用"%I64d",如果拿不准就是用cout好了. 2.在遇到每个数之间有空格,最后一个数后面是换行时可以使用这个小技巧: ; i < n; i++ ) printf(? '\n' : ' ')); 完整代码如下: #d…

题意:求n个'M'型的折线将一个平面分成的最多的面数! 思路:我们都知道n条直线将一个平面分成的最多平面数是 An = An-1 + n+1 也就是f(n) = (n*n + n +2)/2 对于一个'M'型的折线呢?它有四条线,但是由于三个顶点的关系导致划分的平面 的数目减少了9个!所以有递推公式 f(n) = (m*m + m + 2)/2 - 9*n; m = 4*n 最后 f(n) = (8*n+1)*(n-1)+2) 由于 n<=1e12 , 所以回报 long long!那么对于大于…

题意:从任意一个任意一个可走的点开始找一个最长的路,这条路如果有转弯的话, 那么必须是 90度,或者没有转弯! 思路: 首先用dfs将所有可走点开始的 8 个方向上的线段的最长长度求出来 ! step[i][j][k] 表示的是(i,j)沿着k方向一直走到头或者转弯时的最长步数! 最后枚举每一个可走点转弯为90度的路径,找到最长的长度! step[i][j][k1] + step[i][j][k2] 就是 (i, j)这个点 k1 和 k2方向构成90度! #include<iostream>…
