For the B+-tree where M=3 and L=5 shown below, show how an insert of value 80 is handled. || 12 || 50 || / | / | 2 12 50 5 18 65 7 20 70 9 21 72 10 24 78
2. For the B+-tree where M=3 and L=5 shown below, show how an insert of value 77 is handled.
Use the method of splitting the node rather than redistributing between siblings. || 24 || 75 || / | / | / | || 10 || 16 || || 41 || 50 || || 84 || 90 || | / \ / | \ | \ / | | | | \ | | | 2 10 16 24 41 50 75 84 90 5 11 18 26 42 65 78 86 92 7 14 20 30 45 70 79 87 93 9 47 72 80 81
3. A B+-tree is to be stored on disk whose block size is 2048 bytes. The data records
to be stored are 50 bytes, and their key is 4 bytes. Determine the values for M and L for the B+-tree. Assume pointers are 4 bytes each.
4. For the problem above, how many levels are needed to store 10,000,000 records?

Create the statements to save the contents of the RichTextBox named rtbCurrent. Show a SaveFileDialog named sfdCurrent to get the name of the document from the user.
Solve the following recurrence relations by the method of your choiceT(n) = 1 for n = 4 and T(n) =pnT(pn) + n for n > 4. Argue that the solution to the recurrence T(n) = T(n=3) + T(2n=3) + cn is (n lg n) by appealing to the recursion tree.
Determine which of the following commands is used to create an array?
