Given three numbers from user input, decrement the first number by 1 and increment the third number by 2, Then do the magic calculations as follows: get the sum of the first two numbers, deduct the third number from the second and get the product of the first and third number, then sum up the results of the three magic calculations and finally divide you outcome by 3. Sample run 1: Enter three numbers separated by spaces: 4 2 3 Output: Result of Magic calculations = 5 Sample run 2: Enter three numbers separated by spaces: 2 8 5 Output: Result of Magic calculations = 5 a) Write a Pseudocode to solve the above problem b) Create a flowchart for the above pseudocode
