Apache Kafka with Docker
- Apache Kafka, a robust distributed streaming platform, is essential for building dynamic data pipelines and real-time applications. Pairing it with Docker makes setting up Kafka seamless, empowering developers to explore and innovate effortlessly.
- The process of running Apache Kafka with Docker involves creating a Docker Compose file, spinning up the containers, verifying the container status, creating a topic, and producing/consuming messages.
- To create the Docker Compose file, a GitHub repository is provided as a reference. After running the Docker Compose file, the Kafka container can be verified using the 'docker ps' command.
- To create a topic and produce/consume messages, specific commands need to be executed using the Kafka container ID. This guide provides a straightforward way to experiment with Kafka using Docker.

Given an array and a key element, find the number of continuous elements whose sum is greater than the key element.
- Given an array and a key element, find the number of continuous elements whose sum is greater than the key element.
- Solution: Use the two pointers with sliding window approach to solve the problem.
- Increase the right pointer until the sum is greater than or equal to the key element.
- Then increase the left pointer to the right pointer until the sum is less than the key element. Store the minimum length in a variable.

Given 2 strings, check if they are isomorphic strings.
- The problem can be solved using 2 hash maps.
- Iterate over the strings and map the characters to an index in both hash maps.
- If the entries at the same index in both hash maps are not equal, return false.
- If the loop completes without returning false, then the strings are isomorphic.

Find the minimum element from an array that is sorted and is rotated, solution in C++
- To find the minimum element from a sorted and rotated array, we can use a binary search approach.
- Start by initializing two pointers, 'start' and 'end', representing the start and end indices of the array.
- Perform the binary search until 'start' < 'end'.
- If 'arr[start]' < 'arr[end]', it means the array is not rotated, so the smallest element is 'arr[start]' and we return it.

Given an unsorted linked list, sort the list using merge sort.
- To sort an unsorted linked list using merge sort, we divide the list into smaller parts and then merge them in sorted order.
- Merge sort is a divide and conquer algorithm.
- We can apply merge sort recursively on the linked list to divide it into smaller parts and then merge those parts in sorted order.
- The time complexity of merge sort on linked list is O(n log n).
