Leetcode有效偏旁测试用例有问题吗?

Leetcode paranthes问题基本上需要平衡paranthes 示例1:

输入:s=“()” 输出:真

示例2:

输入:s=“()[]{}” 输出:真

示例3:

输入:s=“(]” 输出:false

但是对于测试用例“{[]}”,即使在我的IDE中输出为true,我也会得到false的输出。

struct Node {
    char data;
    Node* next;
};
Node* top = nullptr;

void push(char a) {
    Node* temp = new Node;
    temp->data = a;
    temp->next = top;
    top = temp;
}

void pop() {
    if (top != nullptr) {
        Node* temp = top;
        top = top->next;
        delete temp;
    }
}

void Print(){
    Node *temp = top;
    while(temp!=NULL){
        cout<<temp->data<<endl;
        temp=temp->next;
    }
}

class Solution {
public:
    bool isValid(string s) {
        for (char c : s) {
            if (c == '(' || c == '{' || c == '[') {
                push(c);
                Print();
            } else {
                if (top == nullptr) return false;
                char topchar = top->data;
                if ((c == ')' && topchar == '(') || (c == '}' && topchar == '{') || (c == ']' && topchar == '[')) {
                    Print();
                    pop();
                    
                } else {
                    return false;
                }
            }
        }
        return top == nullptr;
    }
};

In this image you can clearly see extra '(' braces in stdout which are not given in input

我想知道问题是出在我的逻辑上,还是出在测试用例上,因为在我看来,它工作得很好
