Bug: A naive solution may try all subarrays using nested loops (O(n²) or worse), which is too slow for large inputs. Expected: Use Kadane’s Algorithm (O(n)), which efficiently updates the running sum ...

Abstract: Subarraying techniques are promising for achieving performance and cost tradeoffs in the design of a hybrid analog–digital array. However, previous approaches have paid little attention to ...

Understand what the interviewer is asking for by using test cases and questions about the problem. Established a set (2-3) of test cases to verify their own solution later. Established a set (1-2) of ...

Abstract: For wideband arrays, the contiguous subarray architecture using phase shifters at the element level and true time delays at the subarray level results in higher sidelobes due to subarray ...
