Description On the planet Zoop, numbers are represented in base 62, using the digits 0, 1, . . . , 9, A, B, . . . , Z, a, b, . . . , z where A (base 62) = 10 (base 10) B (base 62) = 11 (base 10) ... z (base 62) = 61 (base 10). Given the digit represe…

TOJ 2776题目链接http://acm.tju.edu.cn/toj/showp2776.html 这题其实就是考虑的周全性...  贡献了好几次WA, 后来想了半天才知道哪里有遗漏.最大的问题就是, 当零头是13的时候, 不一定前面的光盘都刻录到最大值.比如29,16这种情况, 如果前面的刻录最大值,这样就需要3个盘,而最少的却是 2个就够了,(15,14) 即可:知道这种情况,这题基本就可以了: 注意一下这几个数据: 13 15 输出为2 29 16 输出为2 这条题目看起来很容易,但…
