3——of C++枚举

C++枚举类型 总结一下C++里面的枚举类就是为了方便字符表示数据的一种方式吧,java枚举类也差不多 默认情况下,一个枚举变量没赋值的话则编译器赋为0,后面一次加1 枚举类型默认为int类型,也可以赋值其他数字类型 枚举的取值范围就不太纠结,感觉没啥用;枚举和switch配合,很棒 enum ex ......

AtCoder Regular Contest 167——B - Product of Divisors

题目很明显,给定 所有因数的积不断除以最多能除几次。 首先,很容易发现,对于每一对因子,都可以对答案得出B的贡献,设A的因子数目为n。 将A进行质因数分解,PBa1,PBa2,PBa3……PBam,那么因数个数就是质因子加一的乘积。 那么因子对数也就是前者一半。答案就是B乘因子对数除以二注意此处除操 ......

CF367C Sereja and the Arrangement of Numbers

这题首先上来会发现题目中的很多信息都是假的,核心就是问要构造一个\(x\)个点的完全图至少要多长的序列 我们把序列中相邻的两个元素看作图上的一条边,则可以把问题转化为:给一个\(x\)个点的完全图,问至少要走多长的路径才可以遍历图中的所有边至少一次 简单讨论下会发现当\(x\)为奇数时,此时图中每个 ......

CF612E Square Root of Permutation

挺有意思的一个构造题,不过这种排列置换相关的套路感觉都太明显了 首先考虑把原图的每个置换环求出来,稍作观察会发现所有长度为奇数的置换环都可以很容易地构造出对应的\(q\)数组 但长度为偶数的置换环就不能单独构造了,但我们发现可以把两个长度相同且为偶数的置换环交错着合并来得到一个合法的\(q\)数组 ......
