which of the following defines the positive integers divisible by both 3 and 4? Select one: O a. 12 ES and if x e S, then x+4,x+3 €S O b. 12 ES and if x e S, then x-4,x-3 ES O. 12 ES and if x e S, then x+12 ES O d. 12 ES and if x e S, then x+4+3 €S The set of nonempty strings can be recursively defined as follows: base case: if x e I then x e X* inductive step: if wE X* and x e I, then xw e X* which of the following recursive function that returns true if there is an "a" in a string and false otherwise? Select one: O a. check(e)=false and check(xw) = (x==a)acheck(w) O b. check(e)=false and check(xw) = (x==a)vcheck(w) O. check(e)=true and check(xw) = (x==a)^check(w) o d. check(e)=true and check(xw) = (x==a)vcheck(w)
