Write a function to find the longest common prefix string amongst an array of strings.

\n\n

If there is no common prefix, return an empty string "".

\n\n

 

\n

Example 1:

\n\n
\nInput: strs = ["flower","flow","flight"]\nOutput: "fl"\n
\n\n

Example 2:

\n\n
\nInput: strs = ["dog","racecar","car"]\nOutput: ""\nExplanation: There is no common prefix among the input strings.\n
