关于力扣链表题需要本地调试创建链表的情况

我们在练习链表题，力扣官方需要会员，我们又不想开会员，想在本地调试给你们提供的代码
声明：本人也是参考的别人的代码，给你们提供不同语言生成链表
参考链接：参考链接

1、编写代码：

C++版本

#include<iostream>

struct ListNode {
    int val;
    ListNode* next;
    
    ListNode(int value) : val(value), next(nullptr) {}
};

ListNode* createSList(int* nums, int sz) {
    ListNode* head = nullptr;
    ListNode* tail = nullptr;

    for (int i = 0; i < sz; ++i) {
        ListNode* newNode = new ListNode(nums[i]);

        if (tail == nullptr) {
            head = tail = newNode;
        } else {
            tail->next = newNode;
            tail = newNode;
        }
    }

    return head;
}

void destroySList(ListNode* head) {
    while (head != nullptr) {
        ListNode* temp = head;
        head = head->next;
        delete temp;
    }
}

int main() {
    int arr[] = {1, 2, 3, 4, 5, 6};
    int sz = sizeof(arr) / sizeof(arr[0]);

    ListNode* plist = createSList(arr, sz);

    // 在程序结束前释放链表占用的内存
    destroySList(plist);

    return 0;
}

JAVA版本

public class ListNode {
    int val;
    ListNode next;

    ListNode(int value) {
        val = value;
        next = null;
    }
}

public class Main {
    static ListNode createSList(int[] nums) {
        ListNode head = null;
        ListNode tail = null;

        for (int num : nums) {
            ListNode newNode = new ListNode(num);

            if (tail == null) {
                head = tail = newNode;
            } else {
                tail.next = newNode;
                tail = newNode;
            }
        }

        return head;
    }

    static void destroySList(ListNode head) {
        while (head != null) {
            ListNode temp = head;
            head = head.next;
            temp = null;
        }
    }

    public static void main(String[] args) {
        int[] arr = {1, 2, 3, 4, 5, 6};
        ListNode plist = createSList(arr);

        // 在程序结束前释放链表占用的内存
        destroySList(plist);
    }
}

Python版本

class ListNode:
    def __init__(self, value):
        self.val = value
        self.next = None

def create_slist(nums):
    head = None
    tail = None

    for num in nums:
        new_node = ListNode(num)

        if tail is None:
            head = tail = new_node
        else:
            tail.next = new_node
            tail = new_node

    return head

def destroy_slist(head):
    while head is not None:
        temp = head
        head = head.next
        temp = None

arr = [1, 2, 3, 4, 5, 6]
plist = create_slist(arr)

# 在程序结束前释放链表占用的内存
destroy_slist(plist)
