We said that any computer program can be constructed using a single instruction that performs a subtraction and branches on negative. Discuss the accuracy of this statement.

What will be an ideal response?

What will be an ideal response?You will have to do some research to answer this question. An Internet search will reveal that there is a single instruction that can be used to construct all programs; that is, the subtract and branch if less than or equal to zero, often written SBN. This is an oddity in the sense that it is impractical to use because it would create horribly long programs to do even the simplest things. However, it has important theoretical implications for computer science; for example, it implies that all computers are equivalent from a computational point of view.
