1. design a scanner
In Credit Wise, how would you design a scanner to get drivers license? What are the technical components to it? Finally, assess the low-fi design given by the interviewer.
2. Optimize Set Operations
You have used a set to record positions from operation type 1 and sequentially recorded the results for operation type 2. However, you are facing memory limit/time limit issues. How would you optimize the solution to handle large datasets efficiently?
3. Operations on Positions
Given a list of operations with two types: [1,x] marks at position x, and [2,x,size] checks if all the positions in the range [x-size, x) are empty. If they are empty, record '1', otherwise record '0'. Write a function to return the record after running all the operations.
4. Flatten Matrix in Spiral Order and Sum Elements
Write a function to flatten an n*n matrix in spiral order, then return the sum of elements with an index that is divisible by 3 (index%3 == 0).
5. Bank Transfer System Design
Design a bank transfer system. The question did not require detailed exploration.
