What is the calculated time complexity of the function ?

private void MoveDown(int start){ int parent = start; int child = 2 * parent + 1; // use the 2*i+1 formula while ( child < list.size() ){ 

 if ( child + 1 < list.size() && list.get(child).compareTo(list.get(child + 1)) > 0 ) child++; // select the smaller child if ( list.get(child).compareTo(list.get(parent)) >= 0 ) break; // reach the proper place swap(parent, child); parent = child; child = 2 * parent + 1; 

} }
