Question

Write a program to input n numbers and reverse the set of numbers without using functions.

Answer 1

A set is unordered, so it cannot be reversed meaningfully. Therefore, use a list of numbers and print its elements from the last index to the first index without using the reverse() function.

n = int(input("Enter number of elements: "))
numbers = []

for i in range(n):
    number = int(input("Enter a number: "))
    numbers.append(number)

print("Numbers in reverse order:")
i = n - 1
while i >= 0:
    print(numbers[i], end=" ")
    i -= 1
