I have learned the basic difference between foldLeft and reduceLeft foldLeft: initial value has to be passed
Having two simple classes taking Int as an a开发者_JAVA技巧rgument: case class Foo(i: Int) class Bar(j: Int)
UPDATE - Solution Thanks to jacobm for his help, I came up with a solution. // Folding Recursion let reverse_list_3 theList =
I\'m trying to write a function with 4 arguments in python def sequence(operation, sta开发者_StackOverflowrt, n, term):
I\'m trying to create a function that takes one argument (a number) and returns the factorial of that number.
I开发者_如何学JAVA\'m trying to write a function in python that is like: def repeated(f, n): ... where f is a function that takes one argument and n is a positive integer.
I would like to pass in an generated(higher order function)to a method to a ruby method . Something like this
I\'ve been reading about combinators and seen how useful they are (for example, in Haskell\'s Parsec).My problem is that I\'m not quite sure how to use them practically.
I was lo开发者_StackOverflow社区oking at the way fold is defined for immutable.Set: def fold [A1 >: A] (z: A1)(op: (A1, A1) ⇒ A1): A1
I have a number of higher order utility functions that take in a code reference and apply that code to some data.Some of these functions require localizing variables during the execution of the subrou
