```cpp
if( temp == 1 ){
x = read(); y = read(); z = read();
update( 1, x, y, z );
break;
}
```
为什么要加break？

```cpp
if( x <= mid ) ans += query( x << 1, l, r );
if( y > mid ) ans += query( x << 1 | 1, l, r );
```
改为
```cpp
if( l <= mid ) ans += query( x << 1, l, r );
if( r > mid ) ans += query( x << 1 | 1, l, r );
```
