02. Fancy Barcodes от 04. Programming Fundamentals Final Exam - 70/100 в judge

Здравейте, колеги,

Някой може ли да ми помогне да си открия грешката в кода?

Предварително много благодаря!

Условие:

Your first task is to determine if the given sequence of characters is a valid barcode or not.

Each line must not contain anything else but a valid barcode. A barcode is valid when:

It is surrounded by a "@" followed by one or more "#"
It is at least 6 characters long (without the surrounding "@" or "#")
It starts with a capital letter
It contains only letters (lower and upper case) and digits
It ends with a capital letter

Examples of valid barcodes: @###Che46sE@##, @#FreshFisH@#, @###Brea0D@###, @##Che46sE@##

Examples of invalid barcodes: ##InvaliDiteM##, @InvalidIteM@, @#Invalid_IteM@#

Next, you have to determine the product group of the item from the barcode. The product group is obtained by concatenating all the digits found in the barcode. If there are no digits present in the barcode, the default product group is "00".

Examples:

@#FreshFisH@# -> product group: 00

@###Brea0D@### -> product group: 0

@##Che4s6E@## -> product group: 46

Input

On the first line, you will be given an integer n – the count of barcodes that you will be receiving next.

On the following n lines, you will receive different strings.

Output

For each barcode that you process, you need to print a message.

If the barcode is invalid:

"Invalid barcode"

If the barcode is valid:

"Product group: {product group}"

Examples

Input	Output
3 @#FreshFisH@# @###Brea0D@### @##Che4s6E@##	Product group: 00 Product group: 0 Product group: 46
Input	Output
6 @###Val1d1teM@### @#ValidIteM@# ##InvaliDiteM## @InvalidIteM@ @#Invalid_IteM@# @#ValiditeM@#	Product group: 11 Product group: 00 Invalid barcode Invalid barcode Invalid barcode Product group: 00

JS Examples

Input	Output
(["3", "@#FreshFisH@#", "@###Brea0D@###", "@##Che4s6E@##"])	Product group: 00 Product group: 0 Product group: 46
Input	Output
(["6", "@###Val1d1teM@###", "@#ValidIteM@#", "##InvaliDiteM##", "@InvalidIteM@", "@#Invalid_IteM@#", "@#ValiditeM@#"])	Product group: 11 Product group: 00 Invalid barcode Invalid barcode Invalid barcode Product group: 00
