PROGRAMMING:The mystery of room number

There is an unwritten rule for the room numbers of our houses, dormitories, hotels, classrooms and computer rooms, that is, the first few digits of the room number generally refer to the floor, and the last few digits refer to the number of the room on this floor.
It's very convenient for us to find the room.
For the sake of simplicity, it is hereby agreed that:
The number of room number is 0 ~ 9;
The length of room number is less than or equal to 8 digits, and the floor number is less than or equal to 3 digits;
Floor 0, 00 and 020 are allowed.
###Input format:
Enter a string (room number Num) and a positive integer (floor number is k) on one line. The input data has ensured that K must be less than the room number length.
###Output format:
Level = floor number, room = room number
###Input example:
```in
02018 1
```
###Output example:
```out
level=0,room=2018
```
