It has the following signature: void SortByPrice(std::vector<Snack>& list_ref, bool asc). This function should sort the vector list_ref based on the price_ of the Snacks. The sorting should be done in the following order: Ascending if asc is true Descending if asc is false. In both cases if variables have the same value for price_, the sorting should be done based on the name_ in ascending order.
