Solution
The program seems to have problem with isGameOver funtion where it returns 1 2 or 3 even when any of the player or computer wins. Hence, your program iterates for only 1 time.
For an Example, In First Iteration if you choose to place player\'s X mark at 4th location, then your first condition i.e.
if ((isSpaceOccupied(0) == isSpaceOccupied(1)) && (isSpaceOccupied(1) == (isSpaceOccupied(2))) ==\'E\') will be true as all the elements in first row are \'E\'
Inside this if condition, it is being checked that whether isSpaceOccupied(0) is \'X\' or not. In this case it will not be \'X\' as you have placed \'X\' at location 4. Hence, the else part would be executed and the value returned from isGameOver function will be 2.
And the story ends there itself. Player 2 wins because of 3 \'E\' values in first row and 1 \'X\' value at 4th location
