Solution 7 should be correct. The diagonal of -1s is a valid win.
Hope all is well with you, Doug!
@Sean, I think Doug's got it right. He's asking only if the X side (that is +1) is in a winning position. In test 7, the O side (-1) is in a winning position. So the answer given is correct.
Test 7 should return true. There is a diagonal of -1.
Shouldn't Test 7 be y_correct = 1?
To be fair, you didn't mention anything about anti-diagonal in your problem description (test no. 4). Or am I missing something?
