+# Logger Rate Limiter
+
+For the given stream of message requests and their timestamps as input, you must implement a logger rate limiter system 
+that decides whether the current message request is displayed. The decision depends on whether the same message has 
+already been displayed in the last S seconds. If yes, then the decision is FALSE, as this message is considered a 
+duplicate. Otherwise, the decision is TRUE.
+
+> Note: Several message requests, though received at different timestamps, may carry identical messages.
+
+## Constraints
+
+- 1 <= `request.length` <= 10^2
+- 0 <= `timestamp` <= 10^3
+- Timestamps are in ascending order.
+- Messages can be written in lowercase or uppercase English alphabets.
+
+## Examples
+
+![Example 1](./images/examples/request_logger_example_1.png)
+![Example 2](./images/examples/request_logger_example_2.png)
+![Example 3](./images/examples/request_logger_example_3.png)
+
+## Solution
+
+We need to know if a message already exists and keep track of its time limit. When thinking about such problems where 
+two associated values need to be checked, we can use a hash map.
+
+We can use all incoming messages as keys and their respective time limits as values. This will help us eliminate 
+duplicates and respect the time limit of S seconds as well.
+
+Here is how we’ll implement our algorithm using hash maps:
+
+1. Initialize a hash map. 
+2. When a request arrives, check if it’s a new request (the message is not among the keys stored in the hash map) or a 
+   repeated request (an entry for this message already exists in the hash map). If it’s a new request, accept it and add 
+   it to the hash map. 
+3. If it’s a repeated request, compare the difference between the timestamp of the incoming request and the timestamp of 
+   the previous request with the same message. If this difference is greater than the time limit, S, accept it and 
+   update the timestamp for that specific message in the hash map. Otherwise, reject it.

+![Solution 2](./images/solutions/request_logger_solution_2.png)
+![Solution 3](./images/solutions/request_logger_solution_3.png)
+![Solution 4](./images/solutions/request_logger_solution_4.png)
+![Solution 5](./images/solutions/request_logger_solution_5.png)
+
+### Solution Summary
+
+Let’s summarize our optimized algorithm:
+
+1. After initializing a hash map, whenever a request arrives, we check whether it’s a new request or a repeated request
+   after the assigned time limit
+
+2. If the request meets either of the conditions mentioned in the above step, we accept and update the entry associated
+   with that specific request in the hash map. Otherwise, reject the request and return the final decision.
+
+### Time Complexity
+
+The decision function checks whether a message has already been encountered, and if so, how long ago it was encountered.
+Thanks to the use of hash maps, both operations are completed in constant time—therefore, the time complexity of the
+decision function is O(1).
+
+### Space Complexity
+
+The space complexity of the algorithm is O(n), where n is the number of incoming requests that we store.
