Easy
思路： 从头开始比较每个字符串，不等就停止循环即可
代码如下
class Solution {public: string longestCommonPrefix(vector<string>& strs) { if(strs.empty()) return ""; for(int i=0;i<strs[0].length();i++) for(int j=0;j<strs.size();j++){ if(i>=strs[0].length()||strs[0][i]!=strs[j][i]) return strs[0].substr(0,i); } return strs[0]; }}; 0 0
