题意:变形的约瑟夫环模型,每个人有一个数字a,从第K个人开始出列,如果数字是正的,就往后数a个人出列,如果书负数,就往反方向数。然后用最基本的线段树处理约瑟夫环的方法即可但是题目要求的是第x个出列的人的名字,x为1-N中约数最多的数中的最小的那个。这里需要求反素数,即不大于N约数最多的。写起来比较多...

前言
当序列中元素范围比较大时,就不适合使用计数排序。针对这种情况,就有了基数排序,这是一种按位排序。它仍然是以计数排序为基础。
基数排序
基数排序的基数:十进制数的基数自然是10,二进制的基数自然是2。通常有两种按位排序策略:1.高位优先法(most significant digit first,MSD):简单讲就是从高位排起。2.低位优先法(least significant digit first,LSD):它与高位优先相反,从低位排起。从排序效果上看,高位优先比较直观,但却涉及到递归的过程,故...
