Question

A hash map (or dictionary) implemented with separate chaining is exhibiting very poor performance, even with a seemingly good hash function. Operations like insertion and search are taking much longer than expected, approaching O(

  • N in many cases. What is the most likely debugging issue related to the collision resolution strategy?
A The hash function is generating too many unique hash codes.
B The underlying array (for buckets) is too large, leading to sparse data.
C The linked lists (or other data structures) used for chaining are not being properly initialized or managed, leading to all elements being in a single bucket.
D The equals() method (or __eq__ in Python) for the stored objects is not implemented correctly.
E The hashCode() method (or __hash__ in Python) is not implemented for the stored objects.
