示例1: main
import java.math.BigInteger; //导入方法依赖的package包/类
public static void main(String[] args) {
Scanner scann = new Scanner(System.in);
String inputNumber = scann.nextLine();
/*BigInteger mask = BigInteger.valueOf(7L);
mask = mask.shiftLeft(61);*/
BigInteger mask = new BigInteger("e000000000000000", 16);
BigInteger num = new BigInteger(inputNumber);
// System.out.printf("%16s -> %s%n", "mask length", mask.toString(2).length());
// System.out.printf("%16s -> %s%n", "binary mask",mask.toString(2));
// System.out.printf("%16s -> %s%n", "binary num",num.toString(2));
while (mask.compareTo(BigInteger.valueOf(7L)) >= 0){
//System.out.printf("%16s -> %s%n", "mask & num", mask.and(num).toString(2));
boolean treeConsecutiveOnes = Objects.equals(num.and(mask), mask);
boolean treeConsecutiveZeroes = Objects.equals(num.and(mask), BigInteger.ZERO);
if(treeConsecutiveOnes || treeConsecutiveZeroes){
if(treeConsecutiveOnes){
