Assignemnt 1) Every Student has some marks associated with it. Student details contains its id and name. And for Marks, there are subjectId, studentId and number of marks a student scored.

Following are the requirements which is required to gain from above scenario (i.e. Student and marks)

Input:- (subjectId, percentage, pass/fail) Output:- for input pass, evaluate that how much students(id, name) are passed in the inputted subjectId for input fail, evaluate that how much students(id, name) are failed in the inputted subjectId Note:- percentage is the input which defines the minimum passing criteria e.g. Pass count: 15 Fail count: 10

Input:- (subjectId, count, top/bottom) Output:- based on the last input(top/bottom), output the students details who have scored max/min in that subjectId e.g. input: 1 5 top output: Kunal 85 Himanshu 84 Geetika 83 Anmol 82 Mahesh 81

Input:- (top/bottom, count) OutPut:- Overall top/least scorer based on all the subjects score, fetch students name count- input defines that how much students name are to be printed on console e.g. input: top 2

output: Himanshu 75% Geetika 74%

Input:- (percentage, good_scholarship, normal_or_no_scholarship) Output:- two groups of students with the amount of scholarship e.g. input: 85% 2000 500 output: Kunal 2000 Himanshu 500 Geetika 2000 Mahesh 500

Input:- (pass/fail, percentage) count and print the number of students and all names who are passed/fail, Pass or fail would be decided by percentage input field. e.g. input: fail 30 output: Kunal 28% Himanshu 29%

6. Find the student(s) who have scored 95% or above and print its details. input: 95% output: Kunal 95% Himanshu 96% Geetika 97%

7. For every student, find its marks in detail (just like detailed Report card of a student.) Note:- must use groupBy method of List input: reportcard output: Kunal 75 70 80 75 75% Himanshu 74 70 81 75 75% Geetika 70 70 85 75 75%

Developer Notes:

There would be two case classes

1. Student(id: Long, name: String)
2. Marks(subjectId: Int,studentId: Long, marksObtained: float)

In order to fill data in those case classes, either take inputs from a file, or take static inputs. But there must be atleast 5 subjects, and atleast 10 students. e.g. List(Student(1, "Kunal"), Student(2, "Himanshu"), Student(3, "Geetika") ....) List(Marks(1, 1, 95), Marks(2, 1, 75), ...) So basically here Kunal has marks 95 and 75 for the paper 1 and 2 respectively.

Assignemnt 2)

• Find the last element of list with its index value(dont use inbuilt methods to extract last element directly)
• print the table of each element in the List
• aggregate the contents of two lists of same size into a single list List(1,2) and List("a", "b") results List(List(1, "a"), List(2, "b"))
• find sum and multiplication of the list (dont use inbuilt methods)
• apply quicksort and mergesort on the Lists
• implement Stack and Queue using Lists.
