class Solution { public String longestCommonPrefix(String[] strs) { if(strs == null || strs.length == 0){ return ""; } int length = strs[0].length(); int count = strs.length; for(int i =0;i<length;i++){ char c = strs[0].charAt(i); for(int j = 1;j<count;j++){ if(i == strs[j].length() || strs[j].charAt(i) != c){ return strs[0].substring(0,i); } } } return strs[0]; } }
