Consider the following Scala code: def f(collection: List[Int], init_acc: Int): Int = {____ .foldLeft (_______) {(acc, ___________) Rightarrow//work which updates the value of _____ in the next iteration, often based on the current value of both acc and ci}} The following pseudo code represents a similar concept acc = ______ for (_______ in-left-to-right _______) {//work which updates the value of _____ in the next iteration, often based on the current value of both acc and ci} Suppose instead we want the analogous pseudo code for foldRight acc = _______ for (_______ __________ _________) {//work which updates the value of _______ in the next iteration, often based on the current value of both acc and ci}
