1.  网每个信息页面下方都有一个信息被浏览次数统计的计数器，如果让你用你熟悉的代码写一个这样一个支持8位ID统计的计数器，你的思路是怎样的？会怎样写？需要用code实现。

在信息表里添加一个用来记录浏览次数的字段，每请求一次该资源，就将浏览次数字段+1,

操作代码就是执行一条更新浏览次数的sql语句：update  info set view = view +1 where id = 1

2.  网不允许一个人在一天之内发布过于重复或者接近重复信息，如果让你实现一个重复度检测算法判断，你的思路是怎样的？code上怎么写？需要用code实现。

检测最大的匹配字符串长度是否超过某个限制，比如100个字符，如果超过这个长度，就认为是重复信息。

public boolean isSame(String a,String b,int size) {

           StringBuffer tmp = new StringBuffer();

           String maxString = "";

           int max = 0;

           int len = 0;

           char[] aArray = a.toCharArray();

           char[] bArray = b.toCharArray();

           int i = 0;

           int j = 0;

           while(i<aArray.length-max) {

                      j = 0;

                      while(j<(bArray.length-max)) {                                

                                 if(aArray[i]==bArray[j]) {

                                              len = 1;

                                              tmp = new StringBuffer();

                                              tmp.append(aArray[i]);                                        

                                              while((i+len<aArray.length)&&(j+len<bArray.length)&&(aArray[i+len]==bArray[j+len])) {

                                                          tmp.append(aArray[i+len]);

                                                          len++;

                                              }

                                              if(len>max) {

                                                                  max = len;

                                                                  maxString = tmp.toString();

                                              }

                                 }

                                 j++;

                      }

                      i++;

           }        

           if(maxString.length > size){

                      return true;

           }else{

                      return false;

           }
