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:
findNeedle(new Object[] {"hay", "junk", "hay", "hay", "moreJunk", "needle", "randomJunk"})
should return "found the needle at position 5"
