编写一个函数来查找字符串数组中最长的公共前缀字符串。
详见:https://leetcode.com/problems/longest-common-prefix/description/
实现语言:Java
class Solution {
public String longestCommonPrefix(String[] strs) {
if(strs==null||strs.length==0){
return "";
}
String res=new String();
for(int j=0;j<strs[0].length();++j){
char c=strs[0].charAt(j);
for(int i=1;i<strs.length;++i){
if(j>=strs[i].length()||strs[i].charAt(j)!=c){
return res;
}
}
res+=Character.toString(c);
}
return res;
}
}
