SBANK - Sorting Bank Accounts


In one of the internet banks thousands of operations are being performed every day. Since certain customers do business more actively than others, some of the bank accounts occur many times in the list of operations. Your task is to sort the bank account numbers in ascending order. If an account appears twice or more in the list, write the number of repetitions just after the account number. The format of accounts is as follows: 2 control digits, an 8-digit code of the bank, 16 digits identifying the owner (written in groups of four digits), for example (at the end of each line there is exactly one space):

30 10103538 2222 1233 6160 0142 

Banks are real-time institutions and they need FAST solutions. If you feel you can meet the challenge within a very stringent time limit, go ahead! A well designed sorting algorithm in a fast language is likely to succeed.

Input


t [the number of tests <= 5]
n [the number of accounts<= 100 000]
[list of accounts]
[empty line]
[next test cases]

Output


[sorted list of accounts with the number of repeated accounts]
[empty line]
[other results]

@Shantanu Banerjee: thanks for your advice :)

C# LINQ Enumerable.Range - Select - Group - Order, one line solution easy AC.

solved without using maps .....just used array and qsort

If you will use C++ STL, you won't be able to learn new things.
Try to apply a BST for greater knowledge.
It made me learn a lot. :)

learnt a new thing about taking inputs

Simple STL Maps .

left this que 3 months ago when dint knew about STL....
this time :P 16 mins nd STL :)

To be honest this input is broken. I didn't know I need to use scanf("%d\n" , &n) to get number of bank accounts and that costed me lots of WA-s. In the end i looked it up on the forums. Can someone explain me the reason behind this?

very easy use of stl.. use getline in c++

Marek Ch is right. The problem description is incorrect. If an account appears once, then the number of repetitions must be printed as 1 in the answer.
