嘛......判斷偶數就減1，奇數不變，就可以輸出啦~

#include<bits/stdc++.h>
using namespace std;
int str[1005];
main()
{
    int num;
    cin >> num;
    for(int i=0;i<num;i++)
        cin >> str[i]; 

    for(int i=0;i<num;i++)
    {
        if(str[i]%2==0)

        cout << str[i]-1 << " ";

        else

        cout << str[i] << " ";

    }
    cout << endl;
    return 0;
}
