#include<iostream>
using namespace std;

int main()
{
 int n;
 cin >> n;
 int* a = new int[n+1];
 int* b = new int[n+1];
 for (int i = 1; i <= n; i++)
 {
  cin >> a[i];
 }
 for (int i = 1; i <= n; i++)
 {
  if (i == 1)
  {
   b[i] = (a[i] + a[i+1])/2;
  }
  else if (i == n)
  {
   b[n] = (a[n] + a[n - 1]) / 2;
  }
  else
  {
   b[i] = (a[i - 1] + a[i + 1] + a[i]) / 3;
  }
 }
 for (int i = 1; i <= n; i++)
 {
 
   cout << b[i] << " ";
  
 }
 
 return 0;
}

第二个数组可以不用开的嘿嘿，不过内存给的够大，就不改了。
