10. How would you implement a bubble sort algorithm?

Below are the sample answers to some coding related question. For algorithmic answers, time and space complexity would be delved in deep.

1. What is the time complexity of the merge sort algorithm, and how does it work?
   Answer: The time complexity of the merge sort algorithm is O(n*log(n)). Merge sort is a sorting algorithm that works by recursively dividing an array into two halves, sorting each half, and then merging the two sorted halves into a single sorted array. The algorithm compares the first elements of each half and places the smaller one into the new array. This process is repeated until both halves have been completely merged.
2. Write an algorithm to find the shortest path between two nodes in a graph.
   Answer: One way to solve this problem is to use Dijkstra's algorithm, which works by assigning tentative distances to all nodes. Then it selects the node with the smallest tentative distance and updates the distances of all the nodes connected to it. This process is repeated until the destination node is reached. The algorithm ensures that it has found the shortest possible distance to every node before selecting the next smallest node. Time complexity of Djikstra's Algorithm could be calculated as O(E log V)
3. How would you implement a binary search algorithm?
   Answer: A binary search algorithm works by dividing the array into two halve in a sorted array and finding the mid point of array and comparing it with the desired element. If the mid-point is equal to the key, then the element is found, otherwise, depending on whether the key is greater or less than the mid-element, we either search the left or the right half of the array. Steps are:

           int binary_search(int arr[], int l, int r, int x) {          if (r >= l) {            int mid = l + (r - l) / 2;            if (arr[mid] == x)                return mid;            if (arr[mid] > x)                return binary_search(arr, l, mid - 1, x);            return binary_search(arr, mid + 1, r, x);          }          return -1;        }       

4. Write a function to reverse a string of characters.
   Answer: One way to solve this problem is to use a two-pointer approach. We use one pointer to traverse the string from left to right and another pointer to traverse the string from right to left. We then swap the elements at the two pointers until they meet in the middle.

            char* reverse_string(char* str) {          int len = strlen(str);          int i = 0, j = len - 1;          while (i < j) {            char temp = str[i];            str[i] = str[j];            str[j] = temp;            i++; j--;          }          return str;          }      

5. How would you remove duplicates from an array?
   Answer: One way to remove duplicates from an array is to use a hash table. We can pass each element of the array into the hash table to check if it's unique. If the element already exists in the hash table, we skip it; otherwise, we add it to the hash table. At the end, we have a list of unique elements.

              int remove_duplicates(int arr[], int n) {            unordered_set seen;            int i = 0, j = 0;            while (i < n) {              if (seen.find(arr[i]) == seen.end()) {                  seen.insert(arr[i]);                  arr[j] = arr[i];                  j++;              }              i++;          }          return j;          }      

6. What is the difference between a stack data structure and a queue data structure?
   Answer: A stack is a data structure that uses the Last-In-First-Out (LIFO) principle, where the last element added to the stack is the first one to be removed. A queue, on the other hand, uses the First-In-First-Out (FIFO) principle, where the first element added to the queue is the first one to be removed.
7. What is the difference between a linked list and an array?
   Answer: An array is a fixed-size data structure that stores elements in contiguous memory locations. A linked list, on the other hand, is a dynamic data structure that stores elements in nodes that are linked together by pointers. Arrays are faster for random access and have a contiguous memory layout that makes it easier to cache data. Linked lists are faster for inserting and deleting elements and offer more flexibility in the size of the data structure.
8. How would you implement a bubble sort algorithm?
   Answer: A bubble sort algorithm works by iterating through an array and comparing adjacent elements if they are in the wrong order the swap takes place. This sorting continued until no more swapping is required.

              void bubble_sort(int arr[], int n) {            for (int i = 0; i < n-1; i++) {              for (int j = 0; j < n-i-1; j++) {                if (arr[j] > arr[j+1]) {                  swap(arr[j], arr[j+1]);                }              }            }          }        

Design Round

In this round, the interviewer will assess your ability to design and implement a complex system. You may be asked to design a system or solve a specific problem related to the supply chain operations. The following are some sample questions:

1. Design a system to manage inventory levels across multiple warehouses.
2. How would you optimize the supply chain process to reduce costs while ensuring timely delivery?
3. How would you design an inventory forecasting system using AI and Machine Learning algorithms?
4. Design a system to track the progress of a shipment from the origin to the destination.
5. How would you design a system to manage and track supplier performance?
6. How would you redesign a supply chain network to accommodate different modes of transportation?
7. How would you design a system to manage material planning and procurement for a global company with multiple suppliers?
8. How would you design a system to optimize warehouse layout and improve efficiency in material handling?
9. How would you create a sustainable supply chain strategy for a company that is expanding its operations globally?

The following are sample answers for some design-related questions:

1. Design a system to manage inventory levels across multiple warehouses.
   Answer: To design a system to manage inventory levels across multiple warehouses, it is important to have clear visibility of stock levels, orders, and incoming inventory. In addition, the system should allow for inventory optimization, which requires demand forecasting and supply planning. In addition, the system should be able to track inventory movement throughout the network to prevent overstocking or stock-outs. One way to address this is by implementing an ERP system that integrates inventory control and management across all warehouses and distribution centers. This would provide real-time visibility into inventory levels, the location of products, and any inventory movements. An inventory forecasting system that used AI and machine learning algorithms would help predict demand and optimize inventory levels. The system should also be able to generate reports and analytics to help management make data-driven decisions for better inventory optimization and reduced carrying costs.
2. How would you optimize the supply chain process to reduce costs while ensuring timely delivery?
   Answer: To optimize the supply chain process while ensuring timely delivery, one approach is to streamline the process and reduce inventory levels, leading to decreased carrying and transportation costs. Working with top-performing suppliers and optimizing freight schedules would also reduce lead times and transportation costs. Another approach is to digitize workflows and operations, which would increase efficiency and standardization in processes. By using data-driven tools like predictive analytics, companies can identify bottlenecks and inefficiencies in their supply chain and make data-driven decisions to optimize performance. One way to accomplish these goals would be to implement a Transportation Management System (TMS) solution, which integrates with supply chain partners to manage inventory levels, streamline transport logistics, and optimize transportation routes.
3. How would you design an inventory forecasting system using AI and Machine Learning algorithms?
   Answer: To design an inventory forecasting system using AI and Machine Learning algorithms, we would need to follow some steps:
   • Data Collection: Collecting relevant historical sales and inventory data from the company's ERP system and third-party data sources such as economic indicators and past promotions.
   • Data Pre-processing: Cleaning and transforming data into a structure that is amenable to machine learning techniques.
   • Model Selection: Selecting an appropriate model for the business use case. Common models used are ARIMA and LSTM.
   • Model Training and Validation: Training the chosen model with labeled data and validating its accuracy using methods like cross-validation.
   • Prediction: Using a trained model to make inventory level predictions based on current data inputs.
   • Optimization: Incorporating predictions and actual inventory levels into supply chain planning and management while continuously evaluating the model predictions with real-time data. The cycle of data collection, pre-processing, model selection, training, and validation may need to be repeated periodically for the model to remain accurate and up-to-date.
4. Design a system to track the progress of a shipment from the origin to the destination.
   Answer: To design a system to track the progress of a shipment from origin to destination, one should consider the following:
   • GPS enabled tracking technology to monitor shipment progress
