: 程式少列印出1-2+3-4+5-6...........N
: 但總total已經算出
int total = 0;
int reverse = 1;
String sequence = "";
for(int i = 1 ; i <= N ; i++)
{
        sequence += i;
        total += reverse*i;
        reverse *= (-1);
        if(reverse > 0)
                sequence += "+";
        else if(reverse < 0)
                sequence += "-";
        else if(i == N)
                sequence += "=";
}
sequence += total;
print(sequence);
