Inspired by the beautiful "XOV" series from The Bard.
Modified Sudoku rules apply: Place the digits 0-9 once each in every row, column and outlined region. However, there will be one digit in each that does not fit. This digit can vary between rows, columns, and regions and needs to be determined by the solver.
XV: Digits separated by an X sum to 10, those separated by a V sum to 5. Not all Xs and Vs are necessarily given.
Slow Thermos: Digits mustn't decrease along thermometers from bulb to tip.
Solution code: Row 5
