Q: In a dynamic programming approach, what is the primary technique used to optimize recursive solutions?
Solution: Memoization is the technique used in dynamic programming to store the results of expensive function calls and reuse them when the same inputs occur again.
Steps: 6
Step 1: Understand that dynamic programming is a method used to solve problems by breaking them down into simpler subproblems.
Step 2: Recognize that some problems can be solved using recursion, where a function calls itself to solve smaller parts of the problem.
Step 3: Identify that recursive solutions can be inefficient because they may solve the same subproblems multiple times.
Step 4: Learn about memoization, which is a technique that saves the results of expensive function calls.
Step 5: Realize that with memoization, when the same inputs occur again, the stored result can be reused instead of recalculating it.
Step 6: Conclude that memoization optimizes recursive solutions by reducing the number of calculations needed.
