Artificial intelligence with prolog program

Question

Write a prolog program that solves the following problems
1. Construct a rule palindrome which takes a word as a list or characters and checks to see
whether it as a palindrome or not. (A palindrome is a word or phrase that is the same
forwards as it is backwards e.g. radar). It should works as follows:
? - palindrome ( [ n, a, v, a, n ] ).
Yes
? - palindrome ( [ d, u, b, l, i, n ] ).
No
2. Write a predicate replace/4 to replace all occurrences of a given element (second
argument) by another given element (third argument) in a given list (first argument). It
should work as follows:
?- replace ([1, 2, 3, 4, 3, 5, 6, 3], 3, x, List).
List = [1, 2, x, 4, x, 5, 6, x]
Yes
3. Implement a Prolog predicate remove_duplicates/2 that removes all duplicate elements from
a list given in the first argument and returns the result in the second argument position. It should
work as follows:
?- remove_duplicates([a, b, a, c, d, d], List).
List = [b, a, c, d]
Yes
Answer**in commentI want to make sure that the answer is correct

Answer 1

Answer**Q1) Function chekpalindrome(str){
Let str1=”anna
Let str2=”banana”
Let str 3=”kayak”
Checkplindrome(str1)
//true
Checkplindrome(str2)
//false
Checkplindrome(str3)
//true
//0.52ms

}
Function chekpalindrome(str){
Let reversed=
[..str].reverse().jonin(“”)
return str====reversed.}

Return str===reversed}
Q2) funcition checkpladrome(str){
Let le=str.length;
If(le===o||le==1){
return true;
}

If(str[0]===str[le-1]){
Returncheckpalindrome(str.slise(1)}
Return false; };//0.30
Q3) Function chekpalindrome(str){
Let1=str.length;8uy
For(leti=1;i<1/2;i++)
{if(str[1]==str[l-1-i]){
Return false}}
return true;
}//0.20
