The constructed B+ index is shown on the figure below: JT y 25 1 10 16 23 25 X W z 31 36 45 52 61 69 Show the state of the index after each of the following operations: a) Write the missing values x,y,w,z into the initial status of the tree b) Insert entry 47 without redistribution c) Insert entry 20 with redistribution d) What would be the state of the tree after operations a,b,c (all without redistribution) if we used the ISAM index? You can answer this question with text or a drawing of a tree.
