Table

Note:

The second line separates the header and content (only need one - for alignment, but extra ones are added for clarity).

Text aligns to the left by default.

Header separator - with : on both sides aligns header text to the center.

Header separator - with : on the right aligns header text to the right.

Header separator - with : on the left aligns header text to the left.

(Note: In the original syntax, both sides of the table to be enclosed in | , but it is omitted here.)

Header|Header|Header
---|:--:|--:
Content|Content|Content
Content|Content|Content

Example:

Header	Header	Header
Content	Content	Content
Content	Content	Content

---

Code

Inline Code

Use one backtick to surround the code

`Code Content`

Example:

Code Content

Code Blocks

Code blocks are enclosed in three backticks on each side, and the backticks occupy a separate line.

// Use `\` as a placeholder to prevent syntax from taking effect.
\```cpp
Code block...
Code block...
Code block...
\```

Example:

/*
Binary string to decimal
Header:
    #include<iostream>
    using namespace std;
Parameter:
    string s: binary string to be converted
Return:
    long long : decimal number after conversion
Example:
    cout << BinaryToInt("000010101"); //21
*/
long long BinaryToInt(string s) {
    long long sum = 0;
    int k = 0;
    for(int i = s.size()-1; i >= 0; i--) {
        long long q = 1;
        for(int j = 1; j <= k; j++) {
            q *= 2;
        }
        sum += (s[i]-48)*q;
        k++;
    }
    return sum;
}
