Data Structures & Algorithms · Question 1
What is the average-case time complexity of looking up a value by key in a well-distributed hash table?
A
O(n)
B
O(log n)
C
O(1)
D
O(n log n)
✓ Correct — O(1). A hash table computes a bucket index directly from the key, so average-case lookup, insert, and delete are O(1). Each answer ships with a detailed explanation in review mode.
