WebThe root of the Segment Tree represents the whole array A [ 0: N − 1]. Then it is broken down into two half intervals or segments and the two children of the root in turn represent the A [ 0: ( N − 1) / 2] and A [ ( N − 1) / 2 + 1: ( N − 1)]. So in each step, the segment is divided into half and the two children represent those two halves.
