.sum()和.max()不包含在Systemverilog中吗？

integer array [0:9] numbers = '{1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
integer sum;

initial begin
    sum = 0;
    foreach (numbers[i]) begin
        sum = sum + numbers[i];
    end
    $display("Sum: %0d", sum);
end

integer array [0:9] numbers = '{1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
integer max;

initial begin
    max = numbers[0];
    foreach (numbers[i]) begin
        if (numbers[i] > max) begin
            max = numbers[i];
        end
    end
    $display("Max: %0d", max);
end

integer array [0:9] numbers = '{}; // 空数组
integer sum;
integer max;

initial begin
    if (numbers.size() > 0) begin
        sum = 0;
        foreach (numbers[i]) begin
            sum = sum + numbers[i];
        end
        $display("Sum: %0d", sum);
    end else begin
        $display("Array is empty, sum is undefined.");
    end

    if (numbers.size() > 0) begin
        max = numbers[0];
        foreach (numbers[i]) begin
            if (numbers[i] > max) begin
                max = numbers[i];
