🚀 Feature Request

Describe the solution you'd like

I would like to propose the addition of algorithms and problem sets related to the Sliding Window and Two Pointer patterns. These techniques are widely used in solving a variety of problems, particularly in array and string manipulation, as well as in optimizing solutions to problems that involve continuous subarrays, subranges, and subsequences.

Importance:

• Sliding Window Pattern: This technique is incredibly efficient for problems requiring the analysis of a fixed or variable-sized subarray. It reduces the time complexity from brute-force O(n²) to O(n) in many cases, making it ideal for handling large data sets in competitive programming and real-world applications like network traffic analysis, stream processing, and more.
• Two Pointer Pattern: This pattern is pivotal in problems involving sorted arrays or strings, enabling us to efficiently find pairs or triplets that satisfy a particular condition. The technique reduces the need for nested loops, improving time complexity and performance.

Would you like to work on this feature?
