Parameters

seed: Type: T
The initial accumulator value. A neutral value for the fold operation (e.g., empty list, or 0 for adding the elements of this sequence, or 1 for multiplication).

op: Type: System Func T, T, T
A function that takes an element of this sequence and the accumulator, and computes the new accumulator.

Return Value

Type: T
The result of applying op between all the elements and seed.
