24. Module – 02

The chapter discusses memoization and dynamic programming as strategies to optimize recursive computations, particularly in the context of defining functions like Fibonacci. Memoization prevents redundant calculations by storing previously computed results, while dynamic programming eliminates recursion by systematically filling in values based on identified dependencies. Through these strategies, computational efficiency improves significantly, addressing the challenges of overlapping subproblems in recursive definitions.
