11. (12 points) In a newly built 5-story building, each floor of a unit has 2 apartments on the east and west sides: the room numbers on each floor are as shown in the figure. Now, five families, Zhao, Qian, Sun, Li, and Zhou, have moved in. One day, the five of them were chatting in the garden:
Zhao said: “My family is the 3rd to move in, and the 1st to move in lives right across from me.”
Qian said: “Only my family lives on the top floor.”
Sun said: “When my family moved in, the same side of the floor above and below us were already occupied.”
Li said: “My family is the last of the five to move in, and the floor below us is completely empty.”
Zhou said: “My family lives in room 106, room 104 is empty, and room 108 is also empty.”
All of what they said is true. Let the unit digits of the room numbers of the 1st, 2nd, 3rd, 4th, and 5th families to move in be $A$, $B$, $C$, $D$, and $E$ respectively. Then the five-digit number $\overline{\mathrm{ABCDE}}=$ . $\qquad$
【Answer】Solution: According to the analysis, since 104 and 108 are both vacant, and Sun has neighbors both upstairs and downstairs, Sun must live on the left side,

Only the Qian family lives on the top floor, which means the remaining 4 people live in 6 of the 101, 102, 103, 105, 106, 107 units,

The completely vacant floor can only be the first or second floor, so that Sun and the neighbors upstairs and downstairs can all have people.
If the first floor is completely vacant, then Li lives in 103 on the second floor, and Li is the last to move in, so Sun lives in 107, and 105 and 109 were occupied before this, Zhao is the third to move in, so Sun must be the fourth to move in, according to what Qian said,

Qian lives in 109, with neighbors in 105 and 106, Zhou lives in 106, so Zhao lives in 105, and Zhou is the first to move in,

Therefore, the answer is: 69573.
