## 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
|
||
|
|
||
|
```go
|
||
![]()
4 years ago
|
func ReduceInt(a []int, f func(int, int) int) {
|
||
5 years ago
|
|
||
|
}
|
||
|
```
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
Here is a possible program to test your function :
|
||
|
|
||
|
```go
|
||
|
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
