对于线段树的节点：

struct Node
    {
        int len;
        ll val;
        ll lazy;
        Node() : len(0), val(0), lazy(0) {} 
        Node(int x) : val(x), lazy(0) {}
    };

和

struct Node
{
    int len;
    ll val;
    ll lazy;
    Node()
    {
        len = 0;
        val = 0;
        lazy = 0;
    }
    
    Node(int x)
    {
        len = 0;
        val = x;
        lazy = 0;
    }
};

两个构造函数有什么区别吗？
