## 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` . For each element of the slice, it should apply the arithmetic function, save the result and print it. The function will be tested with our own functions `Add, Sub, and Mul` .
### Expected function
```go
Refactor & Beautify & destruction commit
return early, remove else branches, reorder conditions and top-level functions, remove empty lines, remove unnecessary append(), fix typos, stop using testing package, remove dead code, fix mistakes in subjects, tests and solutions, remove disclaimers, reformat comments, simplify solutions, tests, add more instructions to subjects, remove obsolete files, etc.
Some of the reasons behind those modifications will be added to good-practices.en.md
Some of the exercises are now broken, they will have to be fixed, most of them have a "TODO:" comment.

func FoldInt(f func(int, int) int, a []int, n int) {
}
```
### Usage
Here is a possible program to test your function:
```go
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 :
```console
$ go run .
99
558
87
93
0
93
$
```
