Answer 1

#include <iostream>

using namespace std;

int main()
{
    int i, j, n, k=1, aux;
    char a[10][10], v[100];
    cin >> n;
    for (i=1; i<=n; i++)
        for (j=1; j<=n; j++)
            cin >> a[i][j];
    for (i=1; i<=n; i++)
        for (j=1; j<=n; j+=2){
            if (isupper(a[i][j])){
                v[k]=a[i][j];
                k++;
            }
        }
    for (i=1; i<k-1; i++)
        for (j=i+1; j<k; j++)
            if (v[i]>v[j]){
                aux=v[j];
                v[j]=v[i];
                v[i]=aux;
            }
    for (i=1; i<k; i++)
        cout << v[i] << " ";
    return 0;
