（说明会有小数存在！）
Input
each test case contains two numbers A and B.
Output
for each case, if A is equal to B, you should print "YES", or print "NO".
Sample Input
1 2
2 2
3 3
4 3
Sample Output

YES
YES
NO
可以用java大数
import java.math.BigDecimal; import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); BigDecimal a; BigDecimal b; while(in.hasNextBigDecimal()) { a=in.nextBigDecimal(); b=in.nextBigDecimal(); a=a.stripTrailingZeros(); //去掉小数点后面多余的0. b=b.stripTrailingZeros(); if(a.equals(b)) System.out.println("YES"); else System.out.println("NO"); } } }
（stripTrailingZeros）A == B hdu2054
