因为错了啊

int a数据溢出了，改成longlong就好了

include

include

typedef long long real; using namespace std; real count_list_squ(real a,real b) {

real count=0;
for (real i = 1; i <= a; i++) {

return count;

}

for (real i = 1; i <= a; i++) {
	
	for (real j = 1; j <= b; j++) {
		if (i != j) {
			count += (a - i + 1) * (b - j + 1);

	}

return count;
