关于算法特性描述正确的有: Which one is right about algorithm’s characterization: ( there are more than one correct answers )
A.
算法描述中下一步执行的步骤不确定。 The next step in the implementation of the algorithm described is uncertain.
B.
算法的有穷性指算法必须在有限步骤内结束。 The finite nature of algorithms means algorithm must be completed within a limited step.
C.
组成算法的指令可以有限也可能无限。 Instructions which composite algorithms can be infinite or finite
D.
算法保证计算结果的正确性。 Algorithm will ensure the correctness of the calculation results.
