Write program in JavaScript to print Fibonacci series up to 15 Observations

Fibonacci series in 

JavaScript


var limit = prompt("Enter the limit 'n' to generate the Fibonacci series:", " ");

var f1=0;

var f2=1;

document.write("The limit entered to generate the Fibonacci series is: ",limit, "<br/>");

document.write("The Fibonacci series is: ");

document.write("",f1," ");

document.write("",f2," ");
 
var i,f3;

for(i=2; i<limit; i++)
{
f3=f1+f2;
document.write("",f3,", ");
f1=f2;
f2=f3;
}


OutPut :

The limit entered to generate the Fibonacci series is: 20
The Fibonacci series : 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 The limit entered to generate the Fibonacci series is: 15
The Fibonacci series : 0 1 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377,

Palindrome program in Java using BufferedReader

import java.io.*; class Test { public static void main(String[] args) throws IOException { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.print("\nEnter a String : "); String str = br.readLine(); String rev = ""; int n = str.length(); for(int i=n-1 ; i>=0 ; i--) { rev = rev + str.charAt(i); } if(str.equals(rev)) System.out.println("\nGiven string is a palindrome"); else System.out.println("\nGiven string is not a palindrome"); } } Output 1 Enter a String : ABCDDCBA Given string is a palindrome Output 2 Enter a String : abcdabcd Given string is not a palindrome

Generics Array Java does not permit the construction of generic array. Suppose, for example, that we want to design a class that has an array field public class Table<AnyType> { private AnyType[] contents = new AnyType[5]; ... } It's hard to understand, but this is illegal! A workaround is to construct an array of objects with a type-cast: public class Table<AnyType> { private AnyType[] stack = (AnyType[]) new Object[5]; ... } source - http://www.cs.cmu.edu/~adamchik/15-121/lectures/Collections/collections.html

OOPS: Decomposition and Abstraction

When we write a a program and if the the code is expected to be less than few hundred of lines then we can afford to write a monolithic program but if the number of lines increase it becomes difficult  to maintain that program or adding new features to that program.  so how to handle this ? In order to write a program for a problem , the problem should be broken into multiple smaller problems and then each smaller problem should be solved  and make sure that solving all such smaller problem solves the actual , bigger problem. the process of breaking a problem into multiple smaller problem efficiently involves Decomposition and Abstraction. Definitions Decomposition- How to decompose large programming problems into small ones is called decomposition Abstraction - Abstraction is a way to do decomposition productively by changing the level of detail to be considered. In each iteration the irrelevant information can be removed. The process of abstraction can be seen as an app...
