Classic Waterfall Model


This Proposed By R.W. Royce in 1970. it is sequential design process. downwards it is basic SDLC Model. divided the life cycle due to set of phases.
Each Phases Must be completed before the next phases can begin..
output of one phases can be input of one phases. No Overlapping.


Feasibility study

Determine weather if would be financially & technically feasible.
Requirement Understanding the exact Requirement of the custom.

  • Requirement Gathering
  • Requirement Specification


Design

To Transform The Requirement Specification in The SRS document into Structure.

Coding

Design is  Translated into Source Code.

Integrated Testing

all The Module Successfully have been successfully integrated the full working system in up timed.

  1. Alpha Testing - Performed By Development Team.
  2. BETA Testing  - Performed By Friendly Set Of customers.
  3. Acceptation   - The Customer Perform the accept testing to determine weather To accept the deliver Software (or) To Reject.


Deployment

Release The Software.

Maintenance

Maintain the released softwares.

Advantage


  • Simple & Easy To Understand.Processed One Of The Time.
  • Work Well For Smaller Project.


Disadvantages


  • No Feedback for batch.
  • Default To Change Request
  • No Overlapping Phasing.

Run Length Encoding | Programming In Java

  Given a string, Your task is to complete the function   encode   that returns the   run-length encoded  string for the given string. eg  if the input string is “wwwwaaadexxxxxx”, then the function should return “w4a3d1e1x6″. You are required to complete the function  encode  that takes only one argument the string which is to be encoded and returns the encoded string. Example 1: Input: str = aaaabbbccc Output: a4b3c3 Explanation: a repeated 4 times consecutively b 3 times, c also 3 times. Example 2: Input: str = abbbcdddd Output: a1b3c1d4 Your Task: Complete the function  encode()  which takes a character array as an input parameter and returns the encoded string. Expected Time Complexity:  O(N), N = length of a given string. Expected Auxiliary Space:  O(1) Constraints: 1<=length of str<=100 Solution: import java.util.*;   class RLEncoding {    public static void main(String[] args)  ...
