Functions
std::string	operations_research::sat::FormatCounter (int64_t num)
	Prints a positive number with separators for easier reading (ex: 1'348'065).
std::string	operations_research::sat::FormatName (absl::string_view name)
	This is used to format our table first row entry.
std::string	operations_research::sat::FormatTable (std::vector< std::vector< std::string > > &table, int spacing)
int64_t	operations_research::sat::ModularInverse (int64_t x, int64_t m)
int64_t	operations_research::sat::PositiveMod (int64_t x, int64_t m)
	Just returns x % m but with a result always in [0, m).
int64_t	operations_research::sat::ProductWithModularInverse (int64_t coeff, int64_t mod, int64_t rhs)
bool	operations_research::sat::SolveDiophantineEquationOfSizeTwo (int64_t &a, int64_t &b, int64_t &cte, int64_t &x0, int64_t &y0)
int64_t	operations_research::sat::FloorSquareRoot (int64_t a)
	The argument must be non-negative.

void	operations_research::sat::RandomizeDecisionHeuristic (absl::BitGenRef random, SatParameters *parameters)
	Randomizes the decision heuristic of the given SatParameters.
int	operations_research::sat::WeightedPick (absl::Span< const double > input, absl::BitGenRef random)

bool	operations_research::sat::IsNegatableInt64 (absl::int128 x)
	Tells whether a int128 can be casted to a int64_t that can be negated.
