To find the (i, j, k) pairs such that their sum is divisible by 3, we can iterate through all possible values of i, j, and k from 1 to 300 and check if (i + j + k) % 3 == 0.
The total number of valid (i, j, k) pairs is 300 * 300 * 300 = 27,000,000.
The valid pairs can be counted as follows:
1. Count how many numbers in the range 1 to 300 give a remainder of 0, 1, or 2 when divided by 3.
- Remainder 0: 100 numbers (3, 6, ..., 300)
- Remainder 1: 100 numbers (1, 4, ..., 298)
- Remainder 2: 100 numbers (2, 5, ..., 299)

The selector `h1` targets all `<h1>` elements, `.warning` targets all elements with the class "warning", and `#footer` targets the element with the ID "footer".
The HTML DOM (Document Object Model) is a programming interface that represents the structure of an HTML document as a tree of objects, allowing scripts to manipulate the content, structure, and style of web pages dynamically.
You can specify two different sets of link colors using CSS by targeting different states of the link. For example:
```css
a {
color: blue; /* Default link color */
}
a:hover {
color: red; /* Color when hovered */
}
```
You can also use classes to define different sets:
```css
.link-set-1 a {
color: green; /* First set color */
}
.link-set-2 a {
color: orange; /* Second set color */
}
```
An ID selector is a CSS selector that targets an HTML element with a specific ID attribute, using the hash symbol (#) followed by the ID name. For example, `#myId` would select the element `<div id="myId">`.
In a previous project, a client needed a last-minute design change for a presentation. I worked late into the night to revise the layout and ensure it was visually appealing and aligned with their brand. The client was thrilled with the result and expressed gratitude for my dedication.
A commit in Git is a snapshot of changes made to the files in a repository. It contains the modified files, a unique identifier (hash), the author's information, a timestamp, and a commit message describing the changes.
To create and switch to a new branch in Git, use the command:
“`
git checkout -b <branch-name>
“`
To resolve merge conflicts in Git, follow these steps:
1. Identify the files with conflicts by running `git status`.
2. Open the conflicted files in a text editor. Look for conflict markers (`<<<<<<<`, `=======`, `>>>>>>>`).
3. Manually edit the file to resolve the conflicts by choosing which changes to keep or combining them.
4. After resolving, save the file.
5. Stage the resolved files using `git add <filename>`.
6. Complete the merge by committing the changes with `git commit`.
You can view the history of commits by using the command `git log`.
Merge combines two branches by creating a new commit that includes changes from both, preserving the history of both branches. Rebase, on the other hand, moves or combines a sequence of commits to a new base commit, creating a linear history without a merge commit.
