An apple, pear, orange, and banana were placed in four boxes (one fruit in each box). Labels were made on the boxes:

1. An orange is here.
2. A pear is here.
3. If a banana is in the first box, then either an apple or a pear is here.
4. An apple is here.

It is known that none of the labels correspond to reality.

Determine which fruit is in which box. In the answer, record the box numbers sequentially, without spaces, where the apple, pear, orange, and banana are located, respectively (the answer should be a 4-digit number).

Present the answer in LaTex format: \boxed{Your answer}
