I explained that an array stores elements in contiguous memory locations and allows fast access using index values, while a linked list stores elements in non-contiguous memory using pointers. However, I got confused while explaining time complexity and real-life use cases, and I couldn’t clearly justify when a linked list is better than an array, which likely led to my rejection.
