PHP switch statement


PHP switch statement is a better alternative than a large series of if-else-if statements. It can switch in different part of the code based on condition. Here is the general form of a PHP switch statement. 
 
switch(expression){
case value1
executed statement;
break;
case value2
executed statement;
break;
………………
default:
// default statement
}

In the PHP switch statement duplicate case values are not allowed. The expression value checks every case iteratively if a match is found then the following case statement is executed. If none of the cases does not matches the value of the expression, then the default statement is executed.

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
