About Data Structure And Algorithms Using Java
With the growth of Information and Communication Technology, there is a need to develop large and complex software. For developing large software, software developers should have enough proficiency in data structures and algorithms. Further, that software should be platform independent, Internet-enabled, easy to modify, secure, and robust. To meet this requirement object-oriented paradigm has been developed and based on this paradigm the Java programming language emerges as the best programming environment.
Now, Java programming language is being used for mobile programming, Internet programming, and many other applications compatible with distributed systems. This course aims to cover the essential topics of data structures and algorithms and how the same can be implemented using Java programming language. The participants of the proposed course will be able to improve their skills, cope with the current demand of IT industries and solve many problems in their own field of studies.
CRITERIA TO GET A CERTIFICATE
Average assignment score = 25% of the average of the best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
