HTML, short for Hyper Text Markup Language, is the backbone of web pages, serving as the structural foundation that browsers interpret to display content. It utilizes a series of tags to define different elements such as headings, paragraphs, images, links, and more. These tags structure the content, shaping the visual and functional aspects of a webpage.

Key Elements of HTML:

Tags and Elements: HTML relies on tags like <p> for paragraphs, <h1-h6> for headings, <img> for images, and <a> for links, each serving a unique purpose in structuring content.

Attributes: These add additional information to HTML elements, like specifying image sources or defining links’ destinations and class id etc.

SEO Techniques in HTML:

Optimizing HTML content for search engines is vital for visibility. Implementing certain techniques enhances a website’s ranking and organic traffic:

Title Tags and Meta Descriptions: Crafting unique, keyword-rich title tags (<title>) and meta descriptions (<meta>) increases visibility in search engine results.

Semantic HTML: Utilizing proper tags for content helps search engines understand page structure, improving indexing and search relevance.

Mobile Optimization: Ensuring HTML is responsive and mobile-friendly is crucial for improved rankings, considering Google’s mobile-first indexing.

Content Marketing and HTML:

Combining HTML with a robust content strategy amplifies marketing efforts:

Structured Content: Properly structured HTML aids in presenting content in an organized manner, enhancing readability and user experience.

Rich Snippets: Employing structured data markup in HTML can enable rich snippets, enhancing a website’s appearance in search results and attracting more clicks.

Social Media Engagement and HTML:

HTML plays a role in social media strategies:

Open Graph Protocol: Implementing Open Graph meta tags in HTML allows for better control over how content appears when shared on platforms like Facebook, enhancing visibility and engagement.

Twitter Cards: Using Twitter Card markup in HTML enables richer media experiences when shared on Twitter, increasing engagement potential.

Website Optimization with HTML:

Optimizing websites involves HTML-centric strategies:

Page Load Speed: Well-structured HTML contributes to faster page loading, positively impacting user experience and SEO rankings.

Canonical Tags: Utilizing canonical tags in HTML prevents duplicate content issues, consolidating page authority and avoiding SEO penalties.

Data Structures:

Data structures are ways of organizing and storing data so that operations can be performed efficiently. They define how data is organized and accessed in computer science.

Algorithms:

Algorithms are step-by-step procedures or formulas for solving problems. They are the blueprint for carrying out a specific task, providing a sequence of actions to be followed to achieve the desired result.

Array:

An array is a fundamental data structure that stores elements of the same data type in contiguous memory locations. It is a collection of items stored at adjacent memory locations and accessed by indexing. Arrays have a fixed size determined at the time of declaration.

1. Rotate An Array:

Given an integer array nums, rotate the array to the right by k steps, where k is non-negative.

Example 1: Input: nums = [1,2,3,4,5,6,7], k = 3 Output: [5,6,7,1,2,3,4] Explanation: rotate 1 steps to the right: [7,1,2,3,4,5,6] rotate 2 steps to the right: [6,7,1,2,3,4,5] rotate 3 steps to the right: [5,6,7,1,2,3,4]

Example 2: Input: nums = [-1,-100,3,99], k = 2 Output: [3,99,-1,-100] Explanation: rotate 1 steps to the right: [99,-1,-100,3] rotate 2 steps to the right: [3,99,-1,-100]

2. Two Sum

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

Example 1:Input: nums = [2,7,11,15], target = 9 Output: [0,1] Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].

Example 2:Input: nums = [3,2,4], target = 6 Output: [1,2] Example 3:Input: nums = [3,3], target = 6 Output: [0,1]

3. Three Sum

Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0.

Notice that the solution set must not contain duplicate triplets.

Example 1: Input: nums = [-1,0,1,2,-1,-4] Output: [[-1,-1,2],[-1,0,1]] Explanation: nums[0] + nums[1] + nums[2] = (-1) + 0 + 1 = 0. nums[1] + nums[2] + nums[4] = 0 + 1 + (-1) = 0. nums[0] + nums[3] + nums[4] = (-1) + 2 + (-1) = 0. The distinct triplets are [-1,0,1] and [-1,-1,2]. Notice that the order of the output and the order of the triplets does not matter.

Example 2: Input: nums = [0,1,1] Output: [] Explanation: The only possible triplet does not sum up to 0.

Example 3: Input: nums = [0,0,0] Output: [[0,0,0]] Explanation: The only possible triplet sums up to 0.

4. Maximum Sub Array

Given an integer array nums, find the subarray with the largest sum, and return its sum.

Example 1: Input: nums = [-2,1,-3,4,-1,2,1,-5,4] Output: 6 Explanation: The subarray [4,-1,2,1] has the largest sum 6.

Example 2: Input: nums = [1] Output: 1 Explanation: The subarray [1] has the largest sum 1.

Example 3: Input: nums = [5,4,-1,7,8] Output: 23 Explanation: The subarray [5,4,-1,7,8] has the largest sum 23.

5. Intersection of Two Array

Given two integer arrays nums1 and nums2, return an array of their intersection. Each element in the result must be unique and you may return the result in any order.

Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2]

Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4] Output: [9,4] Explanation: [4,9] is also accepted.
