Below, there are a few code fragments and the order of growth of their running times as a function of the number of input elements N.

The order of growth: linear.

for (int N = 1; N <= 100; ++N)
{
    outer = 0;
    inner = 0;
    for (int n = N; n > 0; n /= 2)
    {
        ++outer;
        for (int i = 0; i < n; ++i)
            ++inner;
    }
    // outer: ln(N)
    // inner: 2N
    Console.WriteLine($"N={N}\touter: ({N},{outer})\tinner: ({N},{inner})"); 
}

The order of growth: linear ("staircase")

for (int N = 1; N <= 100; ++N)
{
    outer = 0;
    inner = 0;
    for (int n = 1; n < N; n *= 2)
    {
        outer++;
        for (int i = 0; i < n; ++i)
            inner++;
    }
    // outer: ln(N)
    // inner: N
    Console.WriteLine($"N={N}\touter: ({N},{outer})\tinner: ({N},{inner})");
}

The order of growth: linearithmic

for (int N = 1; N <= 100; ++N)
{
    outer = 0;
    inner = 0;
    for (int n = 1; n < N; n *= 2)
    {
        outer++;
        for (int i = 0; i < N; ++i)
            inner++;
    }
    // outer: ln(N)
    // inner: N*ln(N)
    Console.WriteLine($"N={N}\touter: ({N},{outer})\tinner: ({N},{inner})"); 
}

The above linear "staircase" order of growth can be depicted as follows:
