代码

//AC版
public static void main(String[] args)
{
Scanner s = new Scanner(System.in);
while (s.hasNextBigDecimal())
{
BigDecimal a=s.nextBigDecimal();
BigDecimal b=s.nextBigDecimal();
if (a.compareTo(b)==0)
System.out.println("YES");
else
System.out.println("NO");
}
}
//WA版
public static void main(String[] args)
{
Scanner s = new Scanner(System.in);
while (s.hasNext())
{
String a=s.next();
String b=s.next();
if (a.equals(b))
System.out.println("YES");
else
System.out.println("NO");
}
}
//WA版中 01 1 输出NO
//AC版中 01 1 输出YES
//需要的是数字而不是字符串
//用String的equals不够规范
