Sam and Frodo need to be close. If they are side by side in the array, your function should return true. If there is a name between them, return false.

Examples

middle_earth(["Frodo", "Sam", "Gandalf"]) ➞ true

middle_earth(["Frodo", "Saruman", "Sam"]) ➞ false

middle_earth(["Orc", "Sam", "Frodo", "Legolas"]) ➞ true

Notes

• No matter who comes first, the result must be true if Frodo and Sam are side by side.
• There is only one Sam and one Frodo in the array.
