数组元素查重

数组元素查重,帅选出重复的数据

type person struct {
    name, id_card_no string
}

//家系中的相同人员筛选
func familyHasSamePerson(nodeViewList []*person)([]person) {

    nodeMap := make([]person, 0)
    pList := make([]person, 0)
    for _,node := range nodeViewList {
        if !dbdefault.IsStringNullOrEmpty(node.id_card_no){
            nodeMap = append(nodeMap,person{node.name , node.id_card_no,})
        }
    }

    sort.SliceStable(nodeMap, func(i, j int) bool {
        return nodeMap[i].name+nodeMap[i].id_card_no > nodeMap[j].name+nodeMap[j].id_card_no
    })

    nextPos := 0
    for i := range nodeMap {
        if i == len(nodeMap)-1 {
            if nextPos > 0 {
                pList = append(pList, nodeMap[nextPos])
            }
            return pList
        }
        equalFlag := false
        if nodeMap[i].name+nodeMap[i].id_card_no == nodeMap[i+1].name+nodeMap[i+1].id_card_no {
            equalFlag = true
            nextPos = i+1
            pList = append(pList, nodeMap[i])
        }
        if !equalFlag && nextPos > 0 {
            pList = append(pList, nodeMap[nextPos])
            nextPos = 0
        }
    }

    return pList
}
