5 min readIn Prolog, if you want to execute a specific line of code only once, you can achieve this by using a cut operator (!). The cut operator is used to prevent backtracking in Prolog. By placing the cut operator after the predicate you want to execute only once, you can ensure that the predicate is satisfied only once during the execution of the program. This way, the specified line of code will only be executed once in the Prolog program.

6 min readTo search through terms within a list in Prolog, you can use the built-in predicates member/2 and append/3. First, you can check if a term is a member of a list using the member/2 predicate. If you want to search for a specific term within a list of terms, you can use member(Term, List), where Term is the term you are searching for and List is the list of terms.
