reduce

reduce[reducer: def(a: Int, b: IntTuple) capturing -> Int](t: IntTuple, initializer: Int) -> Int

Apply a reduction function to an IntTuple with an initial value.

This function iterates through each element of the IntTuple and applies the provided reduction function cumulatively, starting with the initializer.

Parameters:

  • ​reducer (def(a: Int, b: IntTuple) capturing -> Int): A function that combines the accumulated result with the next element.

Args:

  • ​t (IntTuple): The IntTuple to reduce.
  • ​initializer (Int): The initial value for the reduction operation.

Returns:

Int: The final accumulated result after applying the reduction function to all elements in the IntTuple.
