Experiments

1 a. Write a Scala program to compute the sum of the two given integer values. If the two values are the

same, then return triples their sum.

b. Write a Scala program to check two given integers, and return true if one of them is 22 or if their sum is 32.

2 a. Write a Scala program to remove the character in a given position of a given string. The given position will be in the range 0...string length -1 inclusive.

b. Write a Scala program to create a new string taking the first 5 characters of a given string and return

the string with the 5 characters added at both the front and back.

3 a. Write a Scala program to print the multiplication table of a given number using a for loop.

b. Write a Scala program to find the largest element in an array using pattern matching

4 a. Write a Scala function to calculate the product of digits in a given number

b. Write a Scala function to check if a given number is a perfect square

5 a. Write a Scala program that creates a subclass Student that extends the Person class. Add a property

called grade and implement methods to get and set it.

b. Write a Scala program that creates a class Triangle with properties side1, side2, and side3. Implement a method isEquilateral to check if the triangle is equilateral.

6 a. Write a Scala program that creates an enum class Color with values for different colors. Use the enum class to represent an object's color.

b. Write a Scala program that creates a class ContactInfo with properties name, email, and address. Create a class Customer that includes a ContactInfo object.

7 a. Write a Scala program to create a set and find the difference and intersection between two sets.

b. Write a Scala program to create a set and find the second largest element in the set.

8 a. Write a Scala program to create a list in different ways.

Note: Use Lisp style, Java style, Range list, Uniform list, Tabulate list

b. Write a Scala program to flatten a given List of Lists, nested list structure.

9 a. Write a Scala program to add each element n times to a given list of integers.

b. Write a Scala program to split a given list into two lists.

10 a. Write a Scala program to swap the elements of a tuple Further print no swapping required if elements are same.

b. Write a Scala program to find non-unique elements in a tuple
