744 - Find Smallest Letter Greater Than Target\.
Easy
Given a characters array `letters` that is sorted in **non-decreasing** order and a character `target`, return _the smallest character in the array that is larger than_ `target`.
**Note** that the letters wrap around.
* 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"
**Constraints:**
* 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.
* `target` is a lowercase English letter.
