Answer 1

(1) 102

附代码：

#include

using namespace std;

int main()

{

x05int a,b,c,d,e,total;

x05d = e = 0;

x05for( a = 1; a < 10; a++ )

x05{

x05x05for( b = 0; b < 10; b++ )

x05x05{

x05x05x05for( c = 0; c < 10; c++ )

x05x05x05{

x05x05x05x05total = 100 * a + 10 * b + c;

x05x05x05x05if( a != b & a != c & b != c & total % ( 2 * ( a + b + c )) == 0 )

x05x05x05x05{

x05x05x05x05x05cout
