【转】2011 Multi-University Training Contest 3 - Host by BIT

摘要： T1:Inverting Cups题意是给出A个杯子，一开始都朝上，每次可以翻B个杯子，问最少需要翻转多少次可以让所有杯子都朝下。分类讨论：首先对于A%B==0一类情况，直接输出。对于A>=3B，让A减到[2B,3B)区间内，翻转次数累加上A/B-2。当A>=2B时，分奇偶讨论：A为奇数B为偶数显然无解；AB同奇偶时最多需要3次，A偶数B奇数最多需要4次。当A<2B时，分奇偶讨论：AB同奇偶时最多需要3次，A奇数B偶数无解，A偶数B奇数时，有F(A,B)=F(A,A-B)成立，可以转换成上面的情况求解即可。具体证明画画图就知道了，将两个B分别放到对称的位置上，想办法调整使得每 阅读全文
