Design the pseudocode for a program that allows a user to enter 10 numbers, then displays them in the reverse order of their entry

Answer 1

for i=1 to 10
read n[i]

for i=10 to 1 step -1
print n[i]

Or, if you don't like counting down,

for i=1 to 10
print n[11-i]

or, depending on the language, the array may be 0-based, but you can allow for that.

Answer 2

Design the logic for a program that allows a user to enter 20 numbers, then displays each number and its difference from the numeric average of the numbers entered.
