Problem Description
Given a positive integer n and the odd integer o and the nonnegative integer p such that n = o2^p.Example
For n = 24, o = 3 and p = 3.
Task
Write a program which for each data set:
reads a positive integer n,
computes the odd integer o and the nonnegative integer p such that n = o2^p,
writes the result.
Input
The first line of the input contains exactly one positive integer d equal to the number of data sets, 1 <= d <= 10. The data sets follow.Each data set consists of exactly one line containing exactly one integer n, 1 <= n <= 10^6.
Output
The output should consists of exactly d lines, one line for each data set.Line i, 1 <= i <= d, corresponds to the i-th input and should contain two integers o and p separated by a single space such that n = o2^p.

3 3思路:
就是一个公式: n = o*2^p. n是输入的,o和p是我们需要求的。 需要注意的是o必须是奇数! 0<=p的。import java.util.Scanner;public class Main{ public static void main(String[] args) { Scanner sc = new Scanner(System.in); int t = sc.nextInt(); while(t-->0){ int n = sc.nextInt(); int a=0; int o=0; for(int p=0;pn){ break; } if(n%a==0){ o=n/a; if(o%2==0){ continue; } a=p; break; } } System.out.println(o+" "+a); } }}
