去集合列表，如何将列表传递给函数？

Question

package main

// You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list.

// Input: (2 -> 4 -> 3) + (5 -> 6 -> 4)

// Output: 7 -> 0 -> 8

import (

    "container/list"

    "fmt"

)

func main() {

    l1 := list.New()

    l1.PushBack(4)

    l1.PushBack(5)

    l1.PushBack(2)

    l2 := list.New()

    l2.PushBack(7)

    l2.PushBack(3)

    l3 := list.New()

    l3 = addTwoNumbers(l1, l2)

    for e := l3.Front(); e != nil; e = e.Next() {

        fmt.Println(e.Value)

    }

}

func addTwoNumbers(l1 list, l2 list) (l3 list) {

    int carry = 0

    l4 := list.New()

    e1 := l1.Front()

    e2 := l2.Front()

    for ;; {

        int sum = carry

        if l1 != nil {

            sum += l1.Value

            l1 = l1.Next()

        }

        if l2 != nil {

            sum += l2.Value

            l2 = l2.Next()

        }

        l4.PushBack(sum % 10)

        carry = sum / 10

        if l1== nil && l2 == nil && carry == 0{

            break

        }

    }

    return l4

}

我有错误：

./addTwoNumbers.go:26: syntax error: unexpected name, expecting semicolon or newline or }

./addTwoNumbers.go:31: syntax error: unexpected name, expecting semicolon or newline or }

但我不知道如何修复它。需要帮忙。谢谢
