本地模拟单链表

package single_listimport ("strconv"
)/*** Definition for singly-linked list.* type ListNode struct {*     Val int*     Next *ListNode* }*/type ListNode struct {Val intNext * ListNode
}
// Add String method to use print
func (l *ListNode) String() string {var res stringfor l != nil {res += strconv.Itoa(l.Val)res += "->"l = l.Next}res += "nil"return res
}func (list *ListNode) Add_single_list (l *ListNode, Val int) *ListNode {if l.Next == nil && l.Val == 0 {l.Val = Valreturn l}temp := new(ListNode)temp.Val = Valtemp.Next = nilfor l.Next != nil {l = l.Next}l.Next = tempreturn l
}

SingleList用法

package mainimport (. "xxxxxxxxx/single_list""fmt"
)func main() {list := new(ListNode)list.Add_single_list(list, 1)list.Add_single_list(list, 4)list.Add_single_list(list, 3)list.Add_single_list(list, 2)list.Add_single_list(list, 5)list.Add_single_list(list, 2)fmt.Println(list)
}
