Pro.ID21889 TitlePower Hungry Cows Title链接http://10.20.2.8/oj/exercise/problem?problem_id=21889 AC0 Submit0 Ratio- 时间&空间限制描述You are to write a program to solve jigsaw puzzles. The input file will contain the dimension of the puzzle, the dimension of the pieces, and the actual pieces of the puzzle. The pieces will be made up of ASCII characters. You are to create an output file which consists of FJ's cows would like to be able to compute integer powers P (1 ≤ P ≤ 20,000) of numbers very quickly, but need your help. Because they're going to be computing powers of very large numbers, they can only keep around two work variables for intermediate results. The first of those work variables is initialized to the number (denoted x) for which they are calculating the power; the other is initialized to 1. The cows can both multiply and divide any pair of the work variables and store the result in any work variable, but all results are stored as integers. For example, if they want to compute x31, one way to perform the calculation is: WV1 WV2 Thus, x31 can computed in six operations. Given the power to be computed and the the number of work variables, find the minimum number of operations to calculate the power. 输入A single line with one integer: P. 输出Description You are to write a program to solve jigsaw puzzles.
