I was given the following question in a programming test but i cannot seem to understand why it could't clear all the test cases. What possible test cases am I missing?
A credit card company charges the customer on each transaction as per the following rules:
- If transaction amount is less than 5000.00,charge is 2.0% of amount.
- If transaction amount is greater than equal to 5000.00,charge is 1.5% of amount.
- If transaction amount is greater than 10000.00,charge is 1.0% of amount.
- If previous transactions for a customer in that month are greater than 50000.00 charge is 0.5% of amount.
- The first two transactions for any month with amount less than equal to 5000.00 are free.
- All charges are rounded off to the next greater whole amount. eg. 9.23 to 10.00.
WAP to calculate the charge.
Input is given as follows: First line contain the number of transactions say N. The next N lines contain the transaction details in order : Transaction date,Customer Name,Amount.
Output: Print charges for transactions in the order of given transactions(one per line).
Eg. Sample input
10
2014-06-13,ABC RETAIL,10000.00
2014-06-14,ABC RETAIL,40000.00
2014-06-20,ABC RETAIL,1000.50
2014-06-23,XYZ RETAIL,9000.00
2014-06-23,ABC RETAIL,5000.00
2014-06-24,ABC RETAIL,100.00
2014-07-12,XYZ RETAIL,900.00
2014-07-13,XYZ RETAIL,55000.00
2014-07-13,XYZ RETAIL,550.00
2014-07-13,ABC RETAIL,105000.00
Sample output :
100.0
400.0
0.0
135.0
0.0
1.0
0.0
550.0
0.0
1050.0
Output Explained :
100.0 (Rule 3 applied)
400.0 (Rule 3 applied)
0.0 (Rule 5 applied for June for ABC RETAIL)
135.0 (Rule 2 applied)
0.0 (Rule 5 applied for July for ABC RETAIL)
1.0 (Rule 4 and 6 applied)
0.0 (Rule 5 applied for August for XYZ RETAIL)
550.0 (Rule 3 Applied)
0.0 (Rule 5 applied for August for xyz RETAIL)
1050.0 (Rule 3 Applied)
