2016 Huawei machine Questions--Simple records

The file name and line number where the code for the error is logged.
Processing:
1. Record up to 8 error records, the same error record (that is, the file name and line number exactly match) only one record, the error count increases; (the file is in a different directory, and the same file name and line number are merged)
2. More than 16 characters of the file name, only the last valid 16 characters of the file, (if the file name is different, but only the file name of the following 16 characters and the same line number, do not merge)
3. Input file may have path, record file name cannot take path

Input Description:

A line or multiline string. Each line includes a path file name, line number, separated by a space.
    File path to Windows format
    Example: E:\V1R2\product\fpgadrive.c 1325

Output Description:

Results are sorted according to the first occurrence of the input, depending on the number of orders, in the same number of times.
If more than 8 records are exceeded, only the first 8 records are printed.
If the file name is longer than 16 characters, only the first 16 characters are printed

Input Example:

E:\V1R2\PRODUCT\FPGADRIVE.C 1325

Output Example:

FPGADRIVE.C 1325 1
