WebA list is either empty or it is composed of a first element (head) and a tail, which is a list itself. In Prolog we represent the empty list by the atom [] and a non-empty list by a term [H T] where H denotes the head and T denotes the tail. 1.01 (*) Find the last element of a … WebAug 16, 2024 · It can be used as a program to find a list's last element: ?- last ( [a,b,c,d,e],X). X = e First, there is the stop predicate, that says that the last element of a list with one element, is that element. The second line says that the last element ( Elem) of a list [_ Tail] is the last element of its tail ( Tail ).
WebIn a list, we can find elements in another way, and these elements will satisfy some constraints: ?- member (A, [23, 45, 67, 12, 222, 19, 9, 6]), B is A*A, B<100 A=9 B=81 ; A=6 B=36 ; no The member definition is written as follows: member (A, [A _]). member (A, [_ S]) :- member (A, S). The "don't care" variable is shown by '_' (underscore). WebWrite each question using prolog program along with description and sample runs. 1.Write a predicate maxl to find max integer of an integer list. 2.Implement predicate mergesort to sort a given list. 3.Write a predicate dispnth to display n-th element of a list. You may assume that input string is always longer than n.
Webz A list can have as many elements as necessary. z A list can be empty; an empty list is denoted as [ ]. z A list can have arguments being of: 1 mixed types, 2 complex structures, i.e. terms, lists, etc., and as a consequence 3 a list can have nested lists (to an arbitrary depth) z a list of k elements can be matched directly against these ... WebJul 9, 2024 · Prolog doesn't know anything about C so the last statement doens't force Prolog to return the i -th element. It can simply return any element because N will match with Num in the recursive call and then set C to Num+1 but that's not a problem because C is not bound by anything. A better way to solve this, is using a decrement counter:
WebA.true if A and B have equal lengths B.true if the first element in A is equal to the first and the last element in B. C.true if the first element in A is equal to the first and the second element in B. D.true if the first element in A is equal to the last element in B. Built-in List Predicates length(List,Length)
