Here's a simple GoLang demonstration showing how to see whether or not a slice contains a value, then how to deduplicate the items in that slice. You can easily run this on the Go Playground, check it out!
package main
import "fmt"
func contains(intSlice []int, searchInt int) bool {
for _, value := range intSlice {
if value == searchInt {
return true
}
}
return false
}
func dedup(intSlice []int) []int {
var returnSlice []int
for _, value := range intSlice {
if !contains(returnSlice, value) {
returnSlice = append(returnSlice, value)
}
}
return returnSlice
}
func main() {
numbers := []int{1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6}
fmt.Println("Numbers:", numbers)
fmt.Println("Numbers contain 5:", contains(numbers, 5))
fmt.Println("Numbers contain 8:", contains(numbers, 8))
fmt.Println("Deduped numbers:", dedup(numbers))
}
