So it's initialized outside the loop when it should be initialized inside the loop. Or conversely, inside the loop when it should be outside the loop. So look carefully at when variables are being initialized.

却忘记了,意思就是它本来应该,是在循环外初始化,但是却是在循环初始化的,所以在初始化变量的时候注意这一点。

All right. Second question: or maybe a better way of saying this, and the general format you're likely to see here is, a test involving a variable name, which must be initialized outside of the loop, and which interior to the loop gets changed, so that the test is going to change.

好，第二个问题：,换种更好的方式来说吧，你们通常喜欢的,方式是，这个测试涉及到一个变量名字，变量在循环外已经被初始化，然后循环内部会改变这个变量的值，因此测试结果会改变。
