About C++ destructors

I have some java experience and am a beginner on C++.

below is my code, its output is:

0 1 2 3 4 5 6 7 8 9
destructor ---s1
8791616 8785704 2
destructor ---s1

I expected the following output:

0 1 2 3 4 5 6 7 8 9
destructor ---abc
0 1 2
destructor ---s1

I can't understand why the destructor releases the first object's resource. How can I print the output I expected?

#include <iostream>
using namespace std;
class Sequence{
    public:
        Sequence(int count=10,string name = "abc");
        void show();
        ~Sequence();

        int* _content;
        int _count;
        string _name;

};

Sequence::Sequence(int count,string name){
    _count = count;
    _content=new int[count];
    _name = name;
    for(int i=0;i<count;i++){
        _content[i]=i;
    }
}

Sequence::~Sequence(){
    cout << "destructor ---"<<_name<<endl;
    delete [] _content;
}

void Sequence::show(){
    for(int i=0;i<_count;i++)
        cout<<_content[i]<<" ";
    cout<<endl;
}

int main(){
    Sequence s1 = Sequence();
    s1.show();
    s1 = Sequence(3,"s1");
    s1.show();
}
