What is algorithm and uses in real life ?

The algorithm is a method to analyze a program step by step. In the process, analysis can 
be a finite number of steps called algorithms.
The algorithm is a set of well-defined computational procedures it takes some input numbers and gives desired output to the user.
"set of procedures" called an algorithm.
Sometimes algorithms are incorrect and correct 
Because algorithms are made by humans it depends on human logic how they mad algorithms.
solving problem algorithms can be different from it 
depends on the user and how the user makes an algorithm to solve the problem because solving methods can be different.
That algorithm that takes less time to solve problems is called the "efficient " algorithm.

Let's understand how we use salve problem:

Example 3. Find the greatest between 2 numbers.

Step 1: Start

Step 2: Take 2 numbers as input, say A, B.

Step 3: Check if(A>B)

Step 4: Then A is greater

Step 5: Print A

Step 6: Else

Step 7: Check if(B>A )

Step 8: Then B is greater

Step 9: Print B

Step 10: End

What is the advantage?
1. Using step procedure is make it easy to handle problems.
2. it does not depend on any programming language it is just a step to make the procedure 
    to handle the manipulation of the algorithm to solve the problem base on the real condition.
3. it is easy to solve a real problem and convert them into many parts that make sense to write in the program 

Disadvantages :

1. Some users make the wrong algorithm which can take a lot of time-consuming to solve problems.
2. if you have a large problem to solve, it becomes difficult to find small time complexity.
3. Giving iteration some time are difficult to 
    handle to make an algorithm.

Block Scope Variable in Java

A block scope refers to variables that are declared within a pair of curly braces {}, such as within methods, loops, or conditionals Demonstration of block scope variable:    int x; // known to all code withing block global declaration   if(x==10) {   // start new scope  int y=20; / / y known only to this block // x and y both here can be used   System.out.println("x and y" + x and "" +y);   x=y*2; } // y =100/ Error! you can't call y here because out of scope here // x  is still known here  System.out.println("x is "+x);                        } }|

Type cast variable in java

    Type casting is the process of converting a variable from one data type to another. This is especially useful when you're working with different numeric types or when dealing with inheritance in object-oriented programming. There are two main types of type casting in Java: 1. Widening Casting (Implicit): This happens automatically when converting a smaller type to a larger type size: int myInt = 9; double myDouble = myInt; 2. Narrowing Casting (Explicit): This must be done manually when converting a larger type to a smaller type: java : double myDouble = 9.78; int myInt = (int) myDouble; 3.Type casting also applies to objects in inheritance hierarchies: java : Animal a = new Dog();  // Upcasting (automatic) Dog d = (Dog) a;   class Test{  public static void main(String args[]){ byte b;  int i=257; double d=323.142; System.out.println("In conversion of byte . ");  b=(byte)i; System.out.println("convertion of double to int. "); i=(int)d; Sy...
