Leetcode 1656. Design an Ordered Stream

type OrderedStream struct {
    index int
    values []string
}


func Constructor(n int) OrderedStream {
    return OrderedStream {
        index: 0,
        values: make([]string, n),
    }
}


func (this *OrderedStream) Insert(idKey int, value string) []string {
    this.values[idKey-1] = value
    ret := []string{}
    for this.index < len(this.values) && this.values[this.index] != "" {
        ret = append(ret, this.values[this.index])
        this.index++
    }
    return ret
}
