: 程式少列印出1-2+3-4+5-6...........N
: 但总total已经算出
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);
