## find-missing-number |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
Write a function that takes an array of numbers and returns the missing number. |
||||||
|
- If the array is empty, return `-1`. |
||||||
|
- If the array contains only one number or there is no missing number, return `-1`. |
||||||
|
- if the array contains more than one missing number, return the minimum missing number. |
||||||
|
|
||||||
|
### Expected function |
||||||
|
```go |
||||||
|
func FindMissingNumber(numbers []int) int { |
||||||
|
// Your code here |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a possible program to test your function: |
||||||
|
|
||||||
|
```go |
||||||
|
package main |
||||||
|
|
||||||
|
import "fmt" |
||||||
|
|
||||||
|
func main(){ |
||||||
|
fmt.Println(FindMissingNumber([]int{1, 2, 5,3, 6, 7, 8, 9, 10})) |
||||||
|
fmt.Println(FindMissingNumber([]int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11})) |
||||||
|
fmt.Println(FindMissingNumber([]int{-10,12,32}) |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
and the output should be: |
||||||
|
|
||||||
|
```console |
||||||
|
$ go run . |
||||||
|
4 |
||||||
|
-1 |
||||||
|
-9 |
||||||
|
``` |
