In general, arrays cannot be combined well with generics, and you cannot instantiate arrays with parameterized types. Erasing removes parameter type information, and arrays must know the exact type they hold. But we can parameterize the array itself.

The efficiency of a tree array is mainly by dividing a line segment into small segments (where each small segment stores the interval of the 2^k size, which reduces the interval and the complexity of the problem to logn), rather than a single
