举一反三
- 已知序列h(n)=[1,2,0,1]，x(n)=[2,2,1,1]，则h(n)⑧x(n)= A: [2,6,5,5,4,1,1,0] B: [2,6,5,5,4,1,2,0] C: [2,6,5,5,4,2,1,0] D: [2,6,5,5,4,0,1,0]
- [A]onto[B]of[C]to[D]into[A/]onto/[B/]of/[C/]to/[D/]into
- 设A={a，b，c}，A上二元关系R={[ a, a ] , [ a, b ],[ a, c ], [ c, c]} , 则s（R）= 。
- 下面代码的输出结果是li = ["hello",'se',[["m","n"],["h","kelly"],'all'],123,446]print(li[2][1][1]) A: ｎ B: ｈ C: ｍ D: kelly
- 下列代码的输出结果是（ ）。li = ["hello",'se',[["m","n"],["h","kelly"],'all'],123,446]print(li[2][1][1]) A: h B: kelly C: n D: m
