Expert Solution
Step 1

Pseudocode for 2.a)

//initialize array
arr[20]
index = 0
for 1 to 20
 //get user input value into array
 arr[index] = input
 index = index + 1

//calculate average
avg = sum(arr) / 20

i = 0
// iterate for 20 numbers
for 1 to 20
 //print each number's difference
 print avg - arr[i]
 i = i+1
