25. def solve(): Unit

    

    Solves constraints present in collected inequalities

    Solves constraints present in collected inequalities

    Constraint solving steps: 1) Assert no variable has both >= and <= inequalities (it can have multiple of the same kind of inequality) 2) Merge constraints of variables having multiple inequalities 3) Forward solve inequalities

    1. Iterate through inequalities top-to-bottom, replacing previously seen variables with corresponding constraint b. For each forward-solved inequality, attempt to remove circular constraints c. Forward-solved inequalities without circular constraints are recorded 4) Backwards solve inequalities
    2. Iterate through successful forward-solved inequalities bottom-to-top, replacing previously seen variables with corresponding constraint b. Record solved constraints
