- reduce(+Predicate, +List, +StartValue, -Result)
- The predicate is first called for the first element of the list, the start value and an intermediate result.
Then it is repeatedly called for the next elements, the intermediate result and a new intermediate result.
The final value is the result when the predicate has been called the last time.
E.g.
reduce(plus, [1,2,3,4], 0, 10) holds.
- range(+M, +N, -Range)
- Generate a list of integers in a given range. E.g. range(5, 0, [5,4,3,2,1,0].
- zip(?List1, ?List2, ?List3)
- Zip the lists 1 and 2 together to get list3.
It behaves like zip in python:
zip([a,b],[1,2],[[a,1],[b,2]]).
- zipm(?List1, ?List2, ?List3)
- Zip the lists 1 and 2 together to get list3.
It behaves similar to zip in python but uses - for concatenation:
zip([a,b],[1,2],[a-1,b-2]).
