reduceint

Instructions

The function should have as parameters a slice of integers, a []int and a function f func(int, int) int. You should apply for each element of the slice the arithmetic function, saving it and printing.

Expected function

func ReduceInt(a []int, f func(int, int) int) {

}

Usage

Here is a possible program to test your function :

package main

func main() {
	mul := func(acc int, cur int) int {
		return acc * cur
	}
	sum := func(acc int, cur int) int {
		return acc + cur
	}
	div := func(acc int, cur int) int {
		return acc / cur
	}
	as := []int{500, 2}
	ReduceInt(as, mul)
	ReduceInt(as, sum)
	ReduceInt(as, div)
}

And its output :
