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.

Student submission:
#include<iostream>

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.

Student submission:
#include<iostream>
using namespace std;
int main(){
    int n;
    cin>>n;
    int arr[n];
    for(int i=0;i<n;i++){
        cin >> arr[i];
    }
    for(int i=(n-1);i>-1;i--){
        cout << arr[i] << " ";
    }
    cout << endl;
    for(int i=0;i<n;i++){
        if(arr[i]%2!=0){
            arr[i]=0;
        }
    }
    for(int i=0;i<n;i++){
        cout << arr[i] << " ";
    }
}
