只能读整型
#includeusing namespace std; template void inline read(T &x) { int f = 1; x = 0; char s = getchar(); while (s < '0' || s > '9') { if (s == '-') f = -1; s = getchar(); } while (s <= '9' && s >= '0') x = x * 10 + (s ^ 48), s = getchar(); x *= f; } template void print(T x) { if (x < 0) { putchar('-'); print(x); return ; } if (x >= 10) print(x / 10); putchar((x % 10) + '0'); } int main() { long long x; read(x); print(x); return 0; }
