Party Lamps
To brighten up the gala dinner of the IOI'98 we have a set of N coloured lamps numbered from 1 to N.
The lamps are connected to four buttons:
- button 1
- when this button is pressed, all the lamps change their state: those that are ON are turned OFF and those that are OFF are turned ON.
- button 2
- changes the state of all the odd numbered lamps.
- button 3
- changes the state of all the even numbered lamps.
- button 4
- changes the state of the lamps whose number is of the form 3K+1 (with K>=0), i.e., 1,4,7,...
There is a counter C which records the total number of button presses.
When the party starts, all the lamps are ON and the counter C is set to zero.
Task
You are given the value of counter C and information on the final state of some of the lamps. Write a program to determine
all the possible final configurations of the N lamps that are consistent with the given information, without repetitions.
Input Data
The file named PARTY.IN
with four lines, describing the number N of lamps available, the number C of
button presses, and the state of some of the lamps in the final configuration.
The first line contains the number N and the second line the final value of counter C. The third line lists the lamp
numbers you are informed to be ON in the final configuration, separated by one space and terminated by the integer -1. The
fourth line lists the lamp numbers you are informed to be OFF in the final configuration, separated by one space and terminated
by the integer -1.
Sample Input
10
1
-1
7 -1
In this case, there are 10 lamps and only one button has been pressed. Lamp 7 is OFF in the final configuration.
Output Data
The file PARTY.OUT
must contain all the possible final configurations (without repetitions) of all the lamps.
Each possible configuration must be written on a different line. Configurations may be listed in arbitrary order.
Each line has N characters, where the first character represents the state of lamp 1 and the last character represents
the state of lamp N. A 0 (zero) stands for a lamp that is OFF, and a 1 (one) stands for a lamp that is ON.
Sample Output
0000000000
0110110110
0101010101
In this case, there are three possible final configurations:
- either all lamps are OFF;
- or lamps 1, 4, 7, 10 are OFF, and lamps 2, 3, 5, 6, 8, 9 are ON;
- or lamps 1, 3, 5, 7, 9 are OFF, and lamps 2, 4, 6, 8, 10 are ON.
Constraints
The parameters N and C are constrained by:
10 <= N <= 100
1 <= C <= 10000
The number of lamps you are informed to be ON, in the final configuration, is less than or equal to 2.
The number of lamps you are informed to be OFF, in the final configuration, is less than or equal to 2.
There is at least one possible final configuration for each input test file.
