举一反三
- 已知有向图G=(V,E),其中V={a,b,c,d,e,f,g},E={<a,b>,<a,c>,<a,d>,<b,e>,<c,e>,<c,f>,<d,f>,<e,g>,<f,g>}G的拓扑序列是( ) A: a,c,d,f,b,e,g B: a,c,b,f,d,e,g C: a,c,d,e,b,f,g D: a,b,e,c,d,f,g
- #F旋律大调音阶: ( ) A: #F #E #D #C B #A #G #F B: #F E D #C B #A #G F C: #F #G #A B #C #D #E #F D: F G A B C D E F
- 广义表((a,b,c,d),e,(f,g))的表尾是()。 A: e,(f,g) B: (e,(f,g)) C: (abcd) D: (),e,(f,g)
- 广义表L = (a, b, (c, (d, e)), (f, g)),L的表尾是() A: g B: (f, g) C: , (c, (d, e)), (f, g) D: (b, (c, (d, e)), (f, g))
- 设图G=(V,E),其中V={a,b,c,d,e,f,g},E={{a,b},{a,c},{b,c},{b,d},{b,e},{c,d},{c,f},{d,e},{d,f},{e,g},{e,f},{f,g},{a,g}},则图G的色数为()。 A: 1 B: 2 C: 3 D: 4
