Extended data:

The problem of pouring water is a classic problem. The solution is to pour cups with different capacities back and forth to get the required capacity. Because the data changes are complicated, it is best to record the remaining water of each quilt after each operation.

A mathematical model can be established to list the Diophantine equation, that is, ax+by+cz = d, and the process is to find the integer solution of the equation. Positive numbers in the solution are filled and negative numbers are empty.
