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.

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