Question: What is the space complexity of a typical dynamic programming solution that uses a 2D table?

Options:

Correct Answer: O(n^2)

Solution:

The space complexity of a typical dynamic programming solution that uses a 2D table is O(n^2), where n is the size of the input.

What is the space complexity of a typical dynamic programming solution that uses a 2D table?

Step 1: Understand what dynamic programming is. It is a method for solving problems by breaking them down into simpler subproblems and storing the results of these subproblems to avoid redundant calculations.
Step 2: Recognize that a 2D table is often used in dynamic programming to store results of subproblems. This table has rows and columns.
Step 3: Identify the size of the 2D table. If the input size is 'n', the table typically has 'n' rows and 'n' columns.
Step 4: Calculate the total number of cells in the 2D table. Since there are 'n' rows and 'n' columns, the total number of cells is n * n, which equals n^2.
Step 5: Understand that the space complexity refers to the amount of memory used by the algorithm. In this case, the space used by the 2D table is proportional to the number of cells.
Step 6: Conclude that the space complexity of a typical dynamic programming solution that uses a 2D table is O(n^2), where n is the size of the input.
