foldint

Instructions

The function should have as parameters a function, f func(int, int) int a slice of integers, slice []int and an int acc int. You should apply for each element of the slice the arithmetic function, saving and printing it. The function will be tested with our own functions Add, Sub, and Mul.

Expected function

func FoldInt(f func(int, int) int, a []int, n int) {

}

Usage

Here is a possible program to test your function:

package main

func main() {
	table := []int{1, 2, 3}
	ac := 93
	FoldInt(Add, table, ac)
	FoldInt(Mul, table, ac)
	FoldInt(Sub, table, ac)
	fmt.Println()

	table = []int{0}
	FoldInt(Add, table, ac)
	FoldInt(Mul, table, ac)
	FoldInt(Sub, table, ac)
}

And its output :
