multorsum

Instructions

Write a function that receives a slice of int and an int representing the initial value as arguments.

The function should go through the slice and for each int check the following restrictions:

• If the int is odd, multiply it by the init value. Return the accumulated value after traversing the entire slice.
• If the int is even, add it to the init value. Return the accumulated value after traversing the entire slice.
• If the slice is empty return 0.

Expected function

func MultOrSum(ints []int, init int) int {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
)

func main() {
	fmt.Println(MultOrSum([]int{1, 2, 3, 4}, 3))
	fmt.Println(MultOrSum([]int{1, 2, 3, 4}, 0))
	fmt.Println(MultOrSum([]int{1, -2, 3, 4}, 0))
}

And its output:

$ go run . | cat -e
19$
10$
-2$
