Regular Expressions - More Exercise - 01. Winning Ticket

Здравейте,

Не успях да си намеря проблема в кода: https://pastebin.com/47kbLaB3

1. Winning Ticket

The lottery is exciting. What is not is checking a million tickets for winnings only by hand. So, you are given the task of creating a program that automatically checks if a ticket is a winner.

You are given a collection of tickets separated by commas and spaces. You need to check every one of them if it has a winning combination of symbols.

A valid ticket should have exactly 20 characters. The winning symbols are '@', '#', '$' and '^'. But for a ticket to be a winner, the symbol should uninterruptedly repeat at least 6 times in both the ticket left half and the ticket right half.

For example, a valid winning ticket should be something like this:

"Cash$$$$$$Ca$$$$$$sh"

The left half "Cash$$$$$$" contains "$$$$$$", which is also contained in the ticket right half "Ca$$$$$$sh". A winning ticket should contain symbols repeating up to 10 times in both halves, which is considered a Jackpot (for example: "$$$$$$$$$$$$$$$$$$$$").

Input

The input will be read from the console. The input consists of a single line containing all tickets separated by commas and one or more white spaces in the format:

"{ticket}, {ticket}, … {ticket}"

Output

Print the result for every ticket in the order of their appearance, each on a separate line in the format:

"invalid ticket" - Invalid ticket
"ticket "{ticket}" - no match" - no match
"ticket "{ticket}" - {match length}{match symbol}" - Match with length 6 to 9
"ticket "{ticket}" - {match length}{match symbol} Jackpot!" - Match with length 10

Constraints

The number of tickets will be in the range [0 … 100].

Examples

Input	Output
Cash$$$$$$Ca$$$$$$sh	ticket "Cash$$$$$$Ca$$$$$$sh" - 6$
$$$$$$$$$$$$$$$$$$$$, aabb , th@@@@@@eemo@@@@@@ey	ticket "$$$$$$$$$$$$$$$$$$$$" - 10$ Jackpot! invalid ticket ticket "th@@@@@@eemo@@@@@@ey" - 6@
validticketnomatch:(	ticket "validticketnomatch:(" - no match

Здравей,

Не прокриваш случая, когато в лявата част имаш 6 символа, но завършва с например 2 от същите символи, а във втората започва с 4 от тези символи.

Например:

^^^^^^Ca^^^^^^shCash

Добавих условие na 18-ред да проверява дали групата от символи се съдържа във втората група:

String symbolGroup = matcher.group("symbol");
String secondPart = ticket.substring(ticket.length()-10);
if(!secondPart.contains(symbolGroup)){
    System.out.printf("ticket \"%s\" - no match%n", ticket);
    continue;
}

Проблема е същия като в тема: https://softuni.bg/forum/20221/04-winning-ticket

Hello! I want to ask you for what type of games does this work? It looks like a lottery. I have always thought that lotteries and casino games have the lowest chance of winning for players. That's why I only use sports betting - https://melbet-ca.com/ It's all legal in Canada and open to any adult fan.
