For example, if target == 'z' and letters == ['a', 'b'], the answer is 'a'.

Example 1:

Input: letters = ["c","f","j"], target = "a"
Output: "c"
Example 2:

Input: letters = ["c","f","j"], target = "c"
Output: "f"
Example 3:

Input: letters = ["c","f","j"], target = "d"
Output: "f"
Example 4:

Input: letters = ["c","f","j"], target = "g"
Output: "j"
Example 5:

Input: letters = ["c","f","j"], target = "j"
Output: "c"

Constraints:

2 <= letters.length <= 104
letters[i] is a lowercase English letter.
