Hints

General

• Tuples are data structures which are arranged in contiguous memory and can hold any data-type.
• Atoms may be used to denote finite states, as this exercise uses :cup, :fluid_ounce, :teaspoon, :tablespoon, :milliliter to denote the units used.
• You may use Kernel or Tuple functions or pattern matching to manipulate the tuples.

1. Get the numeric component from a volume-pair

• Consider using a Kernel module function to return the volume-pair's numeric component.

2. Convert the volume-pair to milliliters

• Use multiple clause functions and pattern matching to reduce conditional control flow logic.
• Implement the function for all units to milliliters, including milliliters to milliliters.

3. Convert the milliliter volume-pair to another unit

• Use multiple clause functions and pattern matching to reduce conditional control flow logic.
• Implement the function for all units to milliliters, including milliliters to milliliters.

4. Convert from any unit to any unit

• Reuse the functions already created to perform the conversion in the convert/2 function.
