Problem Description Claris loves bitwise operations very much, especially XOR, because it has many beautiful features. He gets four positive integers a,b,c,da,b,c,d that satisfies a\leq ba≤b and c\leq dc≤d. He wants to choose two integers x,yx,y that…
zxa and xor 题目连接: http://acm.hdu.edu.cn/showproblem.php?pid=5683 Description zxa had a great interest in exclusive disjunction(i.e. XOR) recently, therefore he took out a non-negative integer sequence a1,a2,⋯,an of length n. zxa thought only doing th…
题目描述 LYK最近在研究位运算,它研究的主要有两个:or和xor.(C语言中对于|和^) 为了更好的了解这两个运算符,LYK找来了一个2^n长度的数组.它第一次先对所有相邻两个数执行or操作,得到一个2^(n-1)长度的数组.也就是说,如果一开始时a[1],a[2],…,a[2^n],执行完第一次操作后,会得到a[1] or a[2],a[3] or a[4] ,…, a[(2^n)-1] or a[2^n]. 第二次操作,LYK会将所有相邻两个数执行xor操作,得到一个2^(n-2)长度的数…
