Problem: You are given a sequence of integers. Your task is to reverse the sequence, print it, and then replace all odd numbers in the original sequence with 0 and print the modified sequence.



Your Task

1. Read an integer N representing the number of elements.
2. Read N integers into an array/vector.
3. Print the elements in reverse order.
4. Traverse the original array and replace every odd number with 0.
5. Print the updated array after replacement.



Input Format

- An integer N.
- N integers representing the elements.



Output Format

- First line: Print the array in reverse order with spaces.
- Second line: Print the modified array where all odd numbers are replaced by 0.

Assumptions on Input

- 1 <= N <= 10^5
- Elements are integers.

Problem: You are given a sequence of integers. Your task is to reverse the sequence, print it, and then replace all odd numbers in the original sequence with 0 and print the modified sequence.



Your Task

1. Read an integer N representing the number of elements.
2. Read N integers into an array/vector.
3. Print the elements in reverse order.
4. Traverse the original array and replace every odd number with 0.
5. Print the updated array after replacement.



Input Format

- An integer N.
- N integers representing the elements.



Output Format

- First line: Print the array in reverse order with spaces.
- Second line: Print the modified array where all odd numbers are replaced by 0.

Assumptions on Input

- 1 <= N <= 10^5
- Elements are integers.
