What is memoization ? Write program to implement memoize.

Memoization is the feature of AWS which occurs due to the huge amount of unnecessary requests which in result increases the time of execution. Due to a large number of requests for the same data your account can also get throttled, it also prevents your code from any irrelevant future changes. At present only EC2 APIs are supporting the Memoization. After the activation of the Memoization feature each response made to data will be stored in memory. In case of coached response Memoization response differently. SDK checks for every response before any request with the same credentials. If you disable the Memoization then it will discard all cached responses.
