Given an array of integers, every element appears twice except for one. Find that single one.
Note:
Your algorithm should have a linear runtime complexity. Could you implement it without using extra...

一、异常基础try/except:捕捉由代码中的异常并恢复,匹配except里面的错误,并自行except中定义的代码,后继续执行程序(发生异常后,由except捕捉到异常后,不会中断程序,继续执行try语句后面的程序)try/finally: 无论异常是否发生,都执行清理行为 (发生异常时程序会中...
