{
    long long int nums[100][100];
    char x[90];
    int n, m;
    long long int id, temp;
    cin>>n;
    for(int i=0; i<n; i++)
    {
        cin>>id>>m;
        nums[i][0]=id;
        nums[i][1]=m;
    }
    for(int i=0; i<n; i++)
    {
        for(int j=i+1; j<n; j++)
        {
            if(nums[j][1]>nums[i][1])
            {
                temp=nums[j][0];
                nums[j][0]=nums[i][0];
                nums[i][0]=temp;
                temp=nums[j][1];
                nums[j][1]=nums[i][1];
                nums[i][1]=temp;
            }
        }
    }
    for(int i=0; i<n; i++)
    {
        cout<<nums[i][0]<<" "<<nums[i][1]<<endl;
    }
    return 0;
