题目链接:uva 10837 - A Research Problem 题目大意:给定一个phin.要求一个最小的n.欧拉函数n等于phin 解题思路:欧拉函数性质有,p为素数的话有phip=p−1;假设p和q互质的话有phip∗q=phip∗phiq 然后依据这种性质,n=pk11(p1−1)∗pk22(p2−1)∗⋯∗pkii(pi−1),将全部的pi处理出来.暴力搜索维护最小值,尽管看上去复杂度很高,可是由于对于垒乘来说,增长很快,所以搜索范围大大被缩小了. #include <cstdi…
Uva 101 the block problem 题目大意: 输入n,得到编号为0~n-1的木块,分别摆放在顺序排列编号为0~n-1的位置.现对这些木块进行操作,操作分为四种. 1.move a onto b:把木块a.b上的木块放回各自的原位,再把a放到b上: 2.move a over b:把a上的木块放回各自的原位,再把a发到含b的堆上: 3.pile a onto b:把b上的木块放回各自的原位,再把a连同a上的木块移到b上: 4.pile a over b:把a连同a上木块移到含b的…
