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 :
$ go run .
1000
502
250
