Top Trading Company
Your company grows now. And you are trading with many
companies. So, you are recording transactions of n
companies in a file.
Every company transactions are listed in a line with
a positive or negative number:
- debits are negative (you paid for your buys) and
- credits are positive (you are paid for what you sell).
Because every company have different number of transactions,
the transactions end with a 0 (zero). Then,
your balance is
Balance = (Your income)- (your expenses)
Question:
Write a program that is going to
calculate the total balance
and the company with which you have the most trade
(buys + sells).
Input specification
You will be given an integer (n) the number of
companies where 0 ≤ n ≤ 2000. Then, in
each of the following n lines you will be given:
- Company ID: a string starting with two letters
(from 26 uppercase English chars) and consisting
of 4 digits
- at most 250 floating point
(positive or negative) numbers ending with a
0 (zero).
Output specification:
Show two information: - Total balance:
floating point number with 2 digits precision
- The ID of company with which you have the
most trade (buys + sells)
Note: If there are several
companies with the same most trade amount,
show the company which appears the first.
Sample Input I
4
NL5755 60 70 -25.5 0
AM1966 -25 -60 0
SB9468 82 -20 34 -53 0
TB1567 60.5 -44 66 0
|
Sample Output I:
145 SB9468
|
Explanation: Here are the company
balances according to given information:
|
|
Buys |
Sells |
Balance |
Total Trade |
NL5755 |
-25.5 |
130 |
104.5 |
155.5 |
AM1966 |

SB9468 |

116 |
43 |
189 |
TB1567 |
-44 |
126.5 |
82.5 |
170.5 |
|
Then, total balance is 145 (104.5 - 85 +
43 + 82.5), and the company with which
you have the most trade is SB9468, because total
buys and sells is the max (189).
