+## For exercise 1
+### Steps behind the solve
+I solve this problem by following these steps below:
+ 1. At first, I ask user a question that what is his/her name and store
+    it in a variable as an user input. For ensuring user is not
+    providing blank value I use a `while` loop and warning users until
+    he/she does not provide any input against this question.
+ 2. Then I ask for the age and verify is it in between 10 to 120 years
+    because we don't want that our system is used by a child less than
+    ten, and usually no human being alive after 120 years (except some
+    rare cases).
+ 3. Then I ask for provided his developer status within boolean values that true or false. Here I also ensure that no null value is providing by users using `while` loop.
+ 4. Then I made a dictionary for the roles of users.
+ 5. Then I check those conditions using `if-elif-else` and `print` current role for the user with a greeting message.
+
+### Limitations
+**N.B:**
+Though I check null value. But user can provide any string for his name. Because there are no limitation in the name field except null or empty string. It could be a single character to thousand of characters, with this advantage any malicious user can inject payload or malicious code or script to our program and there is a high risk that it could be compromise by that.
+
+
+## For Exercise 2
+### Steps behind the solve
+1. At first, I extract data from the `config` arguments provided during the function calling.
+2. Then I took a variable called `active_node_count` to store total nodes active in the cluster.
+3. After that, use for loop to count and store active nodes to that variable I took above.
+4. Then I calculate the utilization percentage.
+5. At last, I print the report using f-string.
+
+## For Exercise 3
+### Steps behind the solve
+1. This is a very easy and straight exercise. Here I just calculate total monthly cost and compare it.
+2. Then print the status.
+
+
+## For Exercise 4
+### Steps behind the solve
+1. Here I just use `strip`, `lower` and `replace` functions to sanitized the words and store them to in a new variable called `normalized_outputs` using `append`.
+
+## For Exercise 5
+### Steps behind the solve
+1. This was anothoer easy exercise. The critical think in this problem was this logic `not is_active or cpu_percent > 90.0 and is_production`.
+2. I store the output of this logic in `should_alert` variable.
+3. The I use `if-else` statement to print the message against the output of `should_alert` variable.
+
+
+**That's All - Thank You**
