## reduceint
### Instructions
The function should have as parameters a slice of integers `a []int` and a function `f func(int, int) int`. For each element of the slice, it should apply the function `f func(int, int) int`, save the result and then print it.
### Expected function
```go
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 :
```console
$ go run .
1000
502
250
$
