    Description

    Businesses like to have memorable telephone numbers. One way to make a telephone number memorable is to have it spell a memorable word or phrase. For example, you can call the University of Waterloo by dialing the memorable TUT-GLOP. Sometimes only part of the number is used to spell a word. When you get back to your hotel tonight you can order a pizza from Gino's by dialing 310-GINO. Another way to make a telephone number memorable is to group the digits in a memorable way. You could order your pizza from Pizza Hut by calling their ``three tens'' number 3-10-10-10.

    The standard form of a telephone number is seven decimal digits with a hyphen between the third and fourth digits (e.g. 888-1200). The keypad of a phone supplies the mapping of letters to numbers, as follows:

    A, B, and C map to 2
    D, E, and F map to 3
    G, H, and I map to 4
    J, K, and L map to 5
    M, N, and O map to 6
    P, R, and S map to 7
    T, U, and V map to 8
    W, X, and Y map to 9

    There is no mapping for Q or Z. Hyphens are not dialed, and can be added and removed as necessary. The standard form of TUT-GLOP is 888-4567, the standard form of 310-GINO is 310-4466, and the standard form of 3-10-10-10 is 310-1010.

    Two telephone numbers are equivalent if they have the same standard form. (They dial the same number.)

    Your company is compiling a directory of telephone numbers from local businesses. As part of the quality control process you want to check that no two (or more) businesses in the directory have the same telephone number.

    Input

    The input will consist of one case. The first line of the input specifies the number of telephone numbers in the directory (up to 100,000) as a positive integer alone on the line. The remaining lines list the telephone numbers in the directory, with each number alone on a line. Each telephone number consists of a string composed of decimal digits, uppercase letters (excluding Q and Z) and hyphens. Exactly seven of the characters in the string will be digits or letters.

    Output

    Generate a line of output for each telephone number that appears more than once in any form. The line should give the telephone number in standard form, followed by a space, followed by the number of times the telephone number appears in the directory. Arrange the output lines by telephone number in ascending lexicographical order. If there are no duplicates in the input print the line:

    No duplicates.

    Sample Input

    12
    4873279
    ITS-EASY
    888-4567
    3-10-10-10
    888-GLOP
    TUT-GLOP
    967-11-11
    310-GINO
    F101010
    888-1200
    -4-8-7-3-2-7-9-
    487-3279
    

    Sample Output

    310-1010 2
    487-3279 4
    888-4567 3
      1 /*
      2 问题 输入包含大写字母、-、数字的字符串,将其中的大写字母转换成对应的数字,即标准化后,将出现超过2次的号码标准的形式
      3 按字典序输出。
      4 解题思路 先将字符串存储,将其转化为标准形式存入map映照容器中,其中插入键值和映照数据是注意pair的使用,条件输出即可。
