01. Winning Ticket
Lottery is exciting. What is not, is checking a million tickets for winnings only by hand. So, you are given the task to create a program which 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 in order for a ticket to be a winner the symbol should uninterruptedly repeat for at least 6 times in both the tickets left half and the tickets right half.
For example, a valid winning ticket should be something like this:
"Cash$$$$$$Ca$$$$$$sh"
The left half "Cash$$$$$$" contains "$$$$$$", which is also contained in the tickets right half "Ca$$$$$$sh". A winning ticket should contain symbols repeating up to 10 times in both halves, which is considered a Jackpot (for example: "$$$$$$$$$$$$$$$$$$$$").
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"
• No match - "ticket "{ticket}" - no match"
• Match with length 6 to 9 - "ticket "{ticket}" - {match length}{match symbol}"
• Match with length 10 - "ticket "{ticket}" - {match length}{match symbol} Jackpot!"
Constrains
• Number of tickets will be in range [0 … 100]
