+### Number of operations: 5
+1. modify-overwrite-beta
+2. shift
+3. remove
+### Approach
+1. The modify-overwrite-beta is used in order to concatenate the firstName and the lastName and the complete address into a single string. Also the modify-overwrite-beta operation is used to create a key value pair that gives us the total of orders by using the divide and doubleSum functions.
+2. The shift operation is then used in order to get the desired output in that particular order.
+3. Finally the remove operation is used to remove all the temp variables that were created during the calculation of the total amount of orders.

+1. The modify-overwrite-beta is used in order to split the name in the input json and to add the count of the phone_numbers.
+2. Finally, in the second operation i.e. shift operartion the json is transformed into the desired struture.
