Obtain a "mass cover": two adjacent nodes in the tree such that the cumulative mass of the left node is <= (m) and the cumulative mass of the right node is > (m)
Obtain a "mass cover": two adjacent nodes in the tree such that the cumulative mass of the left node is <= (m) and the cumulative mass of the right node is > (m)
The target mass to cover between two adjacent nodes
a Cover instance with the left and right covering tree nodes. If the (m) was < the mass of the left-most tree node, the left cover value will be None. Similarly if the mass was >= the cumulative mass of the right-most node (equivalent to sum of all node masses in the tree), then the right cover value will be None.
