Please help me with this question.

I need to write this without using 'append'.

Write a program that reads in an integer n, reads n integer numbers from the user, and finally prints the sum of all even numbers, the average of all even numbers, the sum of all odd numbers, the average of all odd numbers, the sum of all the numbers, and the average of all numbers entered. Every negative integer number entry should be skipped and not used in any of the computations.

Thank you
