Question

Haskell coding 3,4 and 5 rad (x : x(y:)) ly rad za 3. (3 points) Which one of the following best describes the recunsive style of the Haskell function rad defined above. A. tail recursive D. backward recunsive E. stepwise refinement F. leftmost outermost B. nonrecursive C. logarithmic recursive 4. (3 points) Which one of the following best describes termination of the Haskell function rad defined above? A. The list argument gets shorter on each recursive call until it becomes empty. B. The list result gets longer on each recursi ve call until it reaches its maximum length. C. x gets snaller on each recursive call until it reaches zero. D. The function does not terminate normally. E. The accummlating parameter converges to zero. 5. (3 points) Which one of the following best describes the execution of the pattern (x : xs0(y: ))in the second clause of the Haskell function rad defined above (assuming all parts of the argument are finite)? A. B. C. D. E. It matches an empty list. It ma tches a one-element list. It matches any list with exactly two elements. It matches any list of two or more elements It matches only lists containing o as their second elements
