Problem
Construct a Btree for the following set of key values: (12, 75, 10, 99, 25, 21, 9, 19, 22, 74, 82). Assume that the tree is initially empty and values are added in the presenting order. Draw the steps for builing the Btree for the case where the number of pointers, not values, that will fit in one node is five or 2d = 4.
