If anybody on either side of them chose to run, they would lose.
任意一个在两边的人要参选,都会失败
And again, a related problem that people run into is side-effects. You call a function and it returns a value, but maybe it, on purpose or on accident, modifies one of the actual parameters.
另外,一个人们常碰到的相关问题,就是副作用,你调用一个函数它返回一个值,但是故意或者无意的,它可能会修改一个实参的值。
