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…
