How does memoization enhance the efficiency of the recursive solution to the coin change problem?
- It adds more redundancy to the recursive calls, slowing down the algorithm.
- It has no impact on the efficiency of the recursive solution.
- It increases the time complexity by caching all intermediate results.
- It reduces the number of recursive calls by storing and reusing previously computed results.
Memoization enhances the efficiency of the recursive solution by storing previously computed results in a cache. When a subproblem is encountered again, the algorithm retrieves the result from the cache, reducing the number of redundant recursive calls and improving overall performance.
