Can you find the needle in the haystack?
Write a function findNeedle() that takes an array full of junk but containing one "needle"
After your function finds the needle it should return a message (as a string) that says:
"found the needle at position " plus the index it found the needle, so:
Example(Input --> Output)
["hay", "junk", "hay", "hay", "moreJunk", "needle", "randomJunk"] --> "found the needle at position 5"
def find_needle(haystack)
"found the needle at position #{haystack.index('needle')}"
end
