此题的样例3

PARAM T C
B = T
A = 4
IF A < 4 THEN(
	IF B > 3 THEN
		Q = 100 + F
	ELSE
		IF C = -1111111111 THEN
			Q = T - A
			IF Q = 0 THEN
				V = V - 1
			END IF
		ELSE
			RETURN I
			E = A
		END IF
	END IF
ELSE
	Q = 1
END IF
RETURN Q

不应该有一个"Line 15: variable Q might not have been initialized"吗？（还是我眼瞎……）
