Fibonacci Series in Java

Welcome back to my blog! Today I will show you how to print a Fibonacci series in Java.
Fibonacci series is a series of numbers where an addition of two numbers produces the next number. That next number is added to its previous number and again produces a next number and so on... The first two numbers of Fibonacci series are 0 and 1.

Now let's see how to write the code for this:

public class Series {
public static void main(String args[]) 
{   
int n1 = 0, n2 = 1, n3icount = 10;   
System.out.println(n1+" "+n2);     //printing 0 and 1     
for(i=2; i<count; i++)     //loop starts from 2 because 0 and 1 are already printed   
{   
  n3n1n2;   
  System.out.println(" "+n3);   
  n1 n2;   
  n2 n3;   
}   
}
        }


It will produce the following output:

0 1
1
2
3
5
8
13
21
34

Verticle Lookup or VLOOKUP is a function in MS Excel that helps a user look for a specific value in a column   based on another particular value in the first column. A simple example: Your boss asks you to find the price of a food item based on its name. Syntax: VLOOKUP(the value you want to look up, where you want to look for it(array/column/table), the column number the value is in, return an approximate or exact match) Let's try to understand it more clearly: Here's a little data set containing a table of my favourite food items.  Step 1: Select a specific cell/text value you would like to search for in the given table/data set. Here, we are looking for the price of Pizza, so we use cell value "Pizza" which is also cell reference A3. We are making sure to use a cell value/re
