Java ：

import java.util.Scanner;public class Main {public static void main(String[] arg){Scanner sc =new Scanner (System.in);int n  =Integer.valueOf(sc.nextLine().trim());String name ,password,line;char[] arr ;int count =0;String[] result =new String[n];for(int i =0;i<n ;i++){    line      =  sc.nextLine().trim();name      =  line.split(" ")[0];password  =  line.split(" ")[1];arr  =password.toCharArray();boolean  changed= false;password="";for(int k=0;k<arr.length;k++){if(arr[k]=='0'){arr[k]='%';changed=true;}else if(arr[k]=='1'){arr[k]='@';changed=true;}else if(arr[k]=='l'){     arr[k]='L';     changed=true;}else if(arr[k]=='O'){arr[k]='o';changed=true;}password += arr[k];}if(changed){result[count]=name+" "+password;count++;}}if(count==0){if(n==1){System.out.println("There is 1 account and no account is modified");}else{                 System.out.println("There are "+n+" accounts and no account is modified");}}else{  System.out.println(count);  for(int i=0;i<count;i++){  System.out.println(result[i]);  }}}}
