Джъдж ми дава 70/100 на задачата Bar Income. Някой има ли идея къде може да е проблема?

1.SoftUni Bar Income
Let`s take a break and visit the game bar at SoftUni. It is about time for the people behind the bar to go home and you are the person who has to draw the line and calculate the money from the products that were sold throughout the day. Until you receive a line with the text "end of shift" you will be given lines of input. But before processing that line you have to do some validations first.
Each valid order should have a customer, product, count, and a price:
- Valid customer's name should be surrounded by '%' and must start with a capital letter, followed by lower-case letters
- Valid product contains any word character and must be surrounded by '<' and '>'
- Valid count is an integer, surrounded by '|'
- Valid price is any real number followed by '$'
The parts of a valid order should appear in the order given: customer, product, count, and price.
Between each part there can be other symbols, except ('|', '$', '%' and '.')
For each valid line print on the console: "{customerName}: {product} - {totalPrice}"
When you receive "end of shift" print the total amount of money for the day rounded to 2 decimal places in the following format: "Total income: {income}".
Input / Constraints
- Strings that you have to process until you receive text "end of shift".
Output
- Print all of the valid lines in the format "{customerName}: {product} - {totalPrice}"
- After receiving "end of shift" print the total amount of money for the day rounded to 2 decimal places in the following format: "Total income: {income}"
- Allowed working time / memory: 100ms / 16MB.

['%George%<Croissant>|2|10.3$', '%Peter%<Gum>|1|1.3$', '%Maria%<Cola>|1|2.4$', 'end of shift'] |
George: Croissant - 20.60 Peter: Gum - 1.30 Maria: Cola - 2.40 Total income: 24.30 |
Each line is valid, so we print each order, calculating the total price of the product bought. At the end we print the total income for the day
|
['%InvalidName%<Croissant>|2|10.3$', '%Peter%<Gum>1.3$', '%Maria%<Cola>|1|2.4', '%Valid%<Valid>valid|10|valid20$', 'end of shift'] |
Valid: Valid - 200.00 Total income: 200.00 |
On the first line, the customer name isn`t valid, so we skip that line. The third line don`t have a valid price. And only the forth line is valid |
@ MartinBG,
може ли кратък коментар на разликата между "greedy and lazy quantifiers".
* или *? . И аз се 4упя тук. 4етох в нета, но не става съвсем ясно.
Благодаря много! :)
До @VasilKos, бях попаднал на едно клипче в ютуб, в което беше даден много добър пример за разликата между двете. Ето линка: https://www.youtube.com/watch?v=c9HbsUSWilw, примерът е към 10та минута.
@VasilKos, при greedy ще се селектират възможно най-много символи от текста, докато при lazy ще се селектира най-кратката част от него, като и в двата случая трябва да са изпълнени всички останали условия на регекса.
Пример:
Текст: a1bxxxxa2b
Регекс: a.*b
Резултат: a1bxxxxa2b (целият текст е матчнат)
Регекс: a.*?b
Резултат: a1bxxxxa2b (матчнати са две групи: a1b и a2b)
