Output: "c"

Example 2:

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

Example 3:

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

• 2 <= letters.length <= 104
• letters[i] is a lowercase English letter.
• letters is sorted in non-decreasing order.
• letters contains at least two different characters.
