Quiz: Digit DP Complexity

Analyzing state space

Check Your Understanding

What is the typical time complexity of Digit DP for counting valid numbers up to N?

  1. A.O(N log N) - sorting-based approach
  2. B.O(N) - we iterate through all numbers
  3. C.O(2^N) - exponential in N
  4. D.O(log N * S * 10) where S is the number of tracked states
