Pro.ID21315 TitleThe Cat in the Hat Title链接http://10.20.2.8/oj/exercise/problem?problem_id=21315 AC1 Submit1 Ratio100.00% 时间&空间限制描述(An homage to Theodore Seuss Geisel) The Cat in the Hat is a nasty creature, A clever cat walks into a messy room which he needs to clean. Instead of doing the work alone, it decides to have its helper cats do the work. It keeps its (smaller) helper cats inside its hat. Each helper cat also has helper cats in its own hat, and so on. Eventually, the cats reach a smallest size. These smallest cats have no additional cats in their hats. These unfortunate smallest cats have to do the cleaning. The number of cats inside each (non-smallest) cat's hat is a constant, N. The height of these cats-in-a-hat is 1/(N+1)times the height of the cat whose hat they are in. The smallest cats are of height one; these are the cats that get the work done. All heights are positive integers. Given the height of the initial cat and the number of worker cats (of height one), find the number of cats that are not doing any work (cats of height greater than one) and also determine the sum of all the cats' heights (the height of a stack of all cats standing one on top of another). 输入The input consists of a sequence of cat-in-hat specifications. Each specification is a single line consisting of two positive integers, separated by white space. The first integer is the height of the initial cat, and the second integer is the number of worker cats. A pair of 0's on a line indicates the end of input. 输出Description (An homage to Theodore Seuss Geisel) The Cat in the Hat is a nasty creature, A clever cat walks into a messy room which he needs to clean.

The first integer is the height of the initial cat, and the second integer is the number of worker cats. A pair of 0's on a line indicates the end of input. Output For each input line (cat-in-hat specification), print the number of cats that are not working, followed by a space, followed by the height of the stack of cats. There should be one output line for each input line other than the "0 0" that terminates input. Sample Input 216 125 Sample Output 31 671 Source 样例输入216 125 样例输出31 671 作者 |
