Example 1:

Input: strs = ["flower","flow","flight"]

Output: "fl"

Explanation: The longest common prefix among "flower", "flow", and "flight" is "fl".

Example 2:

Input: strs = ["dog","racecar","car"]

Output: ""

Explanation: There is no common prefix among "dog", "racecar", and "car", so an empty string is returned.

Example 3:

Input: strs = ["apple"]

Output: "apple"

Explanation: With only one string, that string itself is the longest common prefix.

Example 4:

Input: strs = ["prefix", "preface", "prepare"]

Output: "pre"

Explanation: The common prefix for all three strings is 'pre'.

Example 5:

Input: strs = ["", "bana", "cat"]

Output: ""

Explanation: Since one of the input strings is empty, no common prefix can exist, so an empty string is returned.
