Now I wan to send an email by python code: sending mail(mine) is "myself@foxmail.com"; receiving mail is "test@example.com";
how shall I code for this or need other something?
Just for my clarification, constant space means O(1) space, right?
Anyway, here is a code i have written, please tell me if it uses O(1) space.
void mergeSort() {
ListNode merge = this.head;
this.head = mergeSort(merge);
}

In my program I read values from a configuration array.
First I just used magic constants like this:

is_bool($this->config['ignoreWarnings']) === true
) {

I created a class to operate with concrete table and I want to generalize this code to develop more universal class.
Here is one method of this class:

In my reviews a couple of points come up again and again (and again). It's like somebody is teaching bad practice out there.
As a result a lot of my reviews look very similar (or get terse with my annoyance). It would be nice if there was an area we could have canned quotes that we could link to...
Omit return 0
When a C or C++ program reaches the end of main the compiler will automatically generate code to return 0, so there is no need to put return 0; explicitly at the end of main.
Note: when I make this suggestion, it's almost invariably followed by one of two kinds of comments: "I ...

I attempted to answer this question last week and was thrown off when someone mentioned in a comment that my method would show bias. Eager to prove the naysayer wrong I discovered that things were even worse than he suggested as certain ranges will cause things to break down entirely. So I decide...
I need to make a simple CSV->MySQL script in OOP and I was wondering if there's anything I am doing wrong in a object-oriented sense.

int getArea();
int getCircum();
Also create a program to implement the class
So here is the program with the methods:
