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…

主要考线段树的区间修改和区间查询,这里有一个问题就是这么把一个区间的多种颜色上传给父亲甚至祖先节点,在这里题目告诉我们最多30颜色,那么我们可以把这30中颜色用二进制储存和传给祖先节点,二进制的每一位有0和1两种情况,0表示这个区间不存在这种颜色,1就表示存在,我在这里用到或运算,我们确定一个非叶子节点的值时,可以把它的两个儿子节点的值做或运算,只要某一位有1,那么这一位就是1了,这样就完成了颜色的上传.看代码吧. 建树: struct node{ int w,f; //w是颜色的二进制表示的值…
