MYQ8 - The National Game
Prasanna and Nithin had mastered Thuvax's national game, Tic-Tac-Toe.
Tic-Tac-Toe is a board game for two players, x and o, who take turns (alternatively) marking the spaces in a 3×3 grid with their signs 'x' and 'o' respectively. The x player goes first. The player who succeeds in placing three of his signs in a horizontal, vertical, or diagonal row wins the game and the game stops there.
While returning from a Tic-Tac-Toe tournament, Prasanna and Nithin find a Tic-Tac-Toe like grid. They decide to continue playing from the state the board was in. Help Nithin find whether the next person to move will win/lose or whether the game will result in a tie (assuming both players play optimally), or if such a state is invalid.
Input
First line of the input contains a number T (1 <= T <= 10^6), followed by 4*T lines. The first line of each test case is empty and the next 3 lines show the state of the game.
Output
Print win/lose/tie/invalid for each testcase on a separate line.
Example
Input: 3 oox .x. ..x xox xoo oxx o.. ... ... Output: lose tie invalid
Explanation
Case 1: Player x can win by placing x in either last cell of the middle row, or the first cell of the last row. So the next player, o, cannot prevent him from winning from this state.
Case 2: It is completed game, as you can see no one has won. So, it has ended in a tie.
Case 3: Player x should have started the game. Hence such a state can never be reached.

Keep in mind the judge considers games already done to be valid.

I really cant figure out on which test cases why program fails. I would find it extremely helpful if you could provide some test cases or the number of test cases for which my program fails.

Time limits are 1s-30s. There is at least one test for each 1s and 30s time limits, but there also may by some case with 5s limit. |

The Time limit is 30s, but the judge gives TLE within 5 secs. Is something wrong? |
