Write a function to find the longest common prefix string amongst an array of strings. You are allowed to use a maximum of two loops for this problem. If there is no common prefix, return an empty string ". Example 1: Input: strs = ["flower","flow","flight"] Output: "fl" Еxample 2: Input: strs = ["dog","racecar","car"] Output: ' Explanation: There is no common prefix among the input strings.
