推 dogalan:你題目第二行T0,後面有少打嗎? 02/02 11:40
推 dogalan:如果那邊是process B has the resource vector of (2,0,0) 02/02 11:43
→ dogalan:那就比較好懂了... 02/02 11:44
恩,不好意思,我少打了,已補上

Consider a system with three resource types with the vector Available
initialized to (7,2,6). Suppose at time T0,process A has the resource
vector of (0,1,2),process B has the resource vector of (2,0,0),and
process C has the resource vector of (3,0,3). If process A requests for
extra resource vector of (3,0,0), if is blocked since not enough resource
available for allocation.
Which necessary condition cannot occur for not entering deadlock state?
(A)process B asks for extra (0,1,1) and process C asks for extra (4,0,0)
(B)process B asks for extra (0,1,1) and process C asks for extra (0,0,1)
(C)process B asks for extra (4,1,2) and process C asks for extra (0,0,1)
(D)process B asks for extra (5,2,5) and process C asks for extra (2,1,0)
(E)none of the above
洪兔的題庫書答案是(E)
可是有點不大懂它題目在問什麼?
困惑的點在於沒有給needi
麻煩看懂得大大稍微解釋一下
感謝!
