prefix_product

prefix_product(a: IntTuple) -> IntTuple

Compute the exclusive prefix product of an IntTuple.

This is a convenience wrapper that initializes the prefix product with 1.

Args:

  • ​a (IntTuple): The input IntTuple to compute the prefix product for.

Returns:

IntTuple: A new IntTuple containing the exclusive prefix product of the input.

prefix_product(a: IntTuple, init: Int) -> IntTuple

Compute the exclusive prefix product of an IntTuple with an initial value.

This function delegates to the implementation in prefix_product2.

Args:

  • ​a (IntTuple): The input IntTuple to compute the prefix product for.
  • ​init (Int): The initial value(s) for the prefix product, defaults to 1.

Returns:

IntTuple: A new IntTuple containing the exclusive prefix product of the input.
