我想循環我的表的名稱以添加由符號“ _”定義的關聯。如果表a_b然后存在a則, 。最后，我不必打印名稱中包含“”的表ba = [b]b = [a]_結構體// Table with Fields and Assoctype Table struct { Name string Assoc []Assoc}// Assoc is a name of associated Tabletype Assoc struct { Name string}tables := []string{ "a", "b", "c", "d", "f", "a_b", "a_c", "a_d_f", "c_d", }var tbls []Tablefor _, t := range tables { if strings.Contains(t, "_") { // Split to find "_" like assoc := strings.Split(t, "_") ? // append in struct "Table{Name:a, Assoc: [b,c,d,f]}" // append in struct "Table{Name:b, Assoc: [a]}" // append in struct "Table{Name:c, Assoc: [a,d]}" // append in struct "Table{Name:d, Assoc: [a,c,f]}" // append in struct "Table{Name:f, Assoc: [a,d]}" } else { n := Table{ Name: t, } tbls = append(tbls, n) }}像這樣返回fmt.Println(tbls)：[{a [b,c,d,f]} {b [a]} {c [a,d]} {d [a,c,f]} {f [a,d]}]去游樂場

使用地圖完成上述操作 https://play.golang.org/p/8C5M0L-es6o
package main
import (
"fmt"
"strings"
)
// Table with Fields and Assoc
type Table struct {
Name string
Assoc map[string]int
}
// Assoc is a name of associated Table
// type Assoc struct {
// Name string
// }
func main() {
tables := []string{
"a",
"b",
"c",
"d",
"f",
"a_b",
"a_c",
"a_d_f",
"c_d",
}
var tbls = make(map[string]map[string]int)
for _, t := range tables {
if strings.Contains(t, "_") {
splitAssocs := strings.Split(t, "_")
for i:=0;i<=len(splitAssocs)-2;i++ {
for j:=(i+1);j<=len(splitAssocs)-1;j++{
_, ok := tbls[splitAssocs[i]]
if !ok{
tbls[splitAssocs[i]] = make(map[string]int)
}
_, ok = tbls[splitAssocs[j]]
if !ok{
tbls[splitAssocs[j]] = make(map[string]int)
}
tbls[splitAssocs[i]][splitAssocs[j]] = 1
tbls[splitAssocs[j]][splitAssocs[i]] = 1
}
}
} else {
_, ok := tbls[t]
if !ok{
tbls[t] = make(map[string]int)
}
}
}
fmt.Println(tbls)
}
