寒假16：算法训练 Hankson的趣味题

代码：

import java.util.Scanner;public class Hankson的趣味题 {	public static void main(String[] args) {				Scanner sc=new Scanner(System.in);		int n=sc.nextInt();		int[] data=new int[n];				for (int i = 0; i < data.length; i++) {			int max=0;			int a0=sc.nextInt();			if(a0>max)max=a0;			int a1=sc.nextInt();			if(a1>max)max=a1;			int b0=sc.nextInt();			if(b0>max)max=b0;			int b1=sc.nextInt();			if(b1>max)max=b1;			data[i]=getCount(a0,a1,b0,b1,max);		}		for (int i = 0; i < data.length; i++) {			System.out.PRintln(data[i]);		}	}	private static int getCount(int a0, int a1, int b0, int b1,int max) {		int count=0;		for (int i = 1; i <= max; i++) {			if(gcd(i,a0)==a1&&i*b0/gcd(i,b0)==b1)				count++;		}		return count;	}	private static int gcd(int i, int j) {		if(i%j==0)			return j;		return gcd(j,i%j);	}}
