Counting Based
This category contains an illustrative Dynamic programming problem based on counting. We apply a bottom-up approach to solve the question. First, we calculate the smaller problems of a question. We reach the main problem Using solutions of smaller subproblems. Number of Ways to Convert 2 into N by Squaring, Adding 1, or Multiplying with 2
