How can I determine whether a string is a double fight?

For example, alie is aliex, olai is olain, oupai is onpai, eiyuan is eilo, yolai is yoei, and of course I have a single list. The question is how to filter. People who do not know programming have no idea, but do not know how to do it. They can pay for it... for example:

Alie // Yes
Aliex // No

Olai // Yes
Olain // No

Oupai // Yes
Onpai // No

Eiyuan // Yes
Eilo // No

Yolai // Yes
Yoei // Yes

Of course, I have a single list, and the question is how to filter. People who do not know programming have no idea, but do not know how to do it. They can pay for it .......

By asking a lot of experts, you can basically use it.
