Till receipt

Rebuild what each item brought in from the lines a café till printed during the day.

Every line is in one of these formats:

• NAME @ PRICE sells one item. NAME xQ @ PRICE sells Q of them (Q is a positive integer). PRICE is the price of one item written as digits, a dot and exactly two digits (4.50).
• Either sale format may end with a discount, written as a space and then -N% (N is an integer from 1 to 100). The discount applies to the whole line.
• VOID NAME cancels the most recent sale line for NAME that has not been cancelled yet. If there is no such line, the VOID is ignored.

A name contains only letters and single spaces, it never starts with VOID, and it is case-sensitive.

A sale line is worth Q * price in cents. With a discount of N%, the line is worth (Q * price_in_cents * (100 - N)) divided by 100 and rounded to the nearest cent, with exact halves rounded up. A cancelled line is worth nothing and does not count at all.

Input: lines, a list of strings in the formats above.

Output: a list with one entry [name, cents] for every name that has at least one sale line that was not cancelled, where cents is the sum of those lines' values. List the names in the order in which their first surviving (not cancelled) sale line appears in lines. If nothing survives, return [].
