We want to create a program to check the result of a tic tac toe game. A tic tac toe board is a 3x3 grid. Each position can contain either X or O. The game finishes with a winner when a player creates a straight line of 3 equal symbols. The next 3 boards show finished games with a winner. The empty positions are represented using dots.
X.X OX. .X. OOO .O. .X. ... X.O .XO
In contrast, these 3 boards have not finished with a winner.
OXO X.. ... XXO O.O .X. OOX .XX ..O
The test case consists of 3 lines. Each one with 3 characters (dot, O or X). Note that we are using the letter “O” not the digit zero.
For each test case, write YES if the board finished with a winner or NO if there is no winner.
XXX .OO OO.
XOX OXO OXO
