To reduce disk writing, I have made some changes after Google the solution.
  • Sleeping mode
    1. Check default value
      $ sudo pmset -g | grep hibernatemode hibernatemode 3
    2. Change value
      $ sudo pmset -a hibernatemode 0
    3. Remove sleep image
      $ sudo rm /var/vm/sleepimage
  • Sudden Motion Sensor
    $ sudo pmset -a sms 0

    2. uncheck "Let disk fail sleep when possible"
Hope that could helpful.

How to construct a B+ tree with example

Image
A B+ tree contains n-1 search key values K1K2…….Kn-1 and have n pointers.   In a B+ tree the data are ordered  sequentially.  The leaf node may hold up to n pointers and must hold at least N/2 pointers. The root node must hold at least two pointers, unless the tree consists of only one node.  Now we construct a B+ tree. Construct a B+ tree for the following set of key values: (2,3,5,7,11,17,19,23,29,31) Assume that the tree is initially empty and values are added in ascending order. Construct a B+ tree where the pointer number is Four. Solution: When a node exceeds n-1 search key value then we split it into two nodes. First node contains (ceiling(n-1)/2) values.  2 nd node contains remaining node. Copy the smallest search key value of the second node to the parent node. Let's start, we know each node has N pointer and has N-1 search key values. In our example pointer number is 4, so the search key value is 4-1=3. So each node has 4 pointers and 3 search key value. The first node i
