5.1个人赛解题报告（区间dp，按位与或，图论等水题）

这次5.1打了一场个人赛,已经连赛了三周了,有点疲惫感觉,可能自己太水了,每次都有点小紧张. 这次只解出来三道题,然而有一道按位与按位或的水题不知道思路实在是做题太少,还有就是第一题区间DP,也消耗了不少的时间,但是没有成功的写出来,还是不够熟练啊. 下面写报告 A. System Administrator time limit per test 2 seconds memory limit per test 256 megabytes input standard input output

sdut 2841 Bit Problem (水题)

题目贴这个题是因为看题解有更简单的方法, 我做的时候是直接算的, 也很简单. 贴一下题解吧: 如果一个整数不等于 0,那么该整数的二进制表示中至少有一位是 1. 这个题结果可以直接输出 x - (x&(x-1)); 因为x-1 之后二进制下,就是最右边的1变成了0, 最右边的1的右边所有的0变成了1, 不影响最左边. 我的代码: 1 #include <iostream> 2 #include <cstdio> 3 #include <cstring> 4
