At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions:

1. If program P is to be operated on a day, V can’t be operated on that day.

2. If Q is to be operated on a day, T must be one of the programs to be operated after Q.

3. If R is to be operated on a day, V must be one of the programs to be operated after R.

4. The last program to be operated on any day must be either S or U.
