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

Java:

public class Solution{        public String longestPreString(String[] s):                String pre=s[0];                int i=1;                while(i<s.length){                        while(s[i].indexOf(pre)!=0){                                pre=pre.subString(0,pre.length()-1);                        }                        i++;                }                return pre;}

Python:

class Solution:        def longestPreString(self,s):                pre=s[0]                i=1                while i<len(s):                        while s[i].index(pre)!=0:                                pre=pre[0:len(s)-1]                        i+=1                return pre
