# Return true if the string in the first element of the array contains

# all of the letters of the string in the second element of the array.

# For example, ["hello", "Hello"], should return true because all of the letters

# in the second string are present in the first, ignoring case.

# The arguments ["hello", "hey"] should return false because the string "hello"

# does not contain a "y". Lastly, ["Alien", "line"], should return true because

# all of the letters in "line" are present in "Alien".
