It can be seen that the number, 125874, and its double, 251748, contain exactly the same digits, but in a different order.
Find the smallest positive integer, x, such that 2x, 3x, 4x, 5x, and 6x, contain the same digits.

#多线程-共享全局变量
#多线程之间共享全局变量有两种方式：
#子线程函数使用global关键字来调用函数外全局变量
#列表当作实参传递到线程中
#在一个进程内所有的线程共享全局变量，很方便在多个线程间共享数据
#缺点就是，线程是对全局变量随意遂改可能造成多线程之间对全局变量的混乱（即线程非安全）
# 共享全局变量-global全局变量
#例如：
# from threading import Thread
# from time import sleep
# num=100
# def work1():
# global num
# for i in range(3):
# num+=1
