func IsContainInt(items []int, item int) bool {
    for _, eachItem := range items {
        if eachItem == item {
            return true
        }
    }
    return false
}

func IsContain(items []string, item string) bool {
    for _, eachItem := range items {
        if eachItem == item {
            return true
        }
