Compile Error

我这后面怎么直接省略了（雾
```cpp
int main() {
for (int a = 1 ; a <= n ; ++ a) lim = max(lim,v[a] = re());
build(1,n,1);
for (int op,i,j,k ; m ; -- m) {
op = re(),i = re(),j = re();
switch (op) {
case 1:k = re(),o = 1,printf("%d\n",rank(1,n,1,i,j,k) + o);break;
case 2:k = re(),printf("%d\n",tkth(i,j,k));break;
case 3:update(1,n,1,i,j),v[i] = j;break;
case 4:k = re(),op=fpre(1,n,1,i,j,k),printf("%d\n",op>=0?op:-0x7fffffff);break;
case 5:k = re(),op=fsuc(1,n,1,i,j,k),printf("%d\n",op<=INF?op:0x7fffffff);break;
}
}
return 0;
}
