ACTIVITY 2:

# A is the array and n is the array size

def sum(A,n):

total =0

for i in range(n):

total = total + A [ i ]

return total

LOOPS ( READ QUESTION AND SOLVE IT AS REQUIRED)

If diff is 0, then guess is correct and the program outputs a message indicating that the user guessed the correct number.

1. If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num).

2. If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num).

3. If diff is greater than or equal to 15 and less than 30, the program outputs the message indicating that the guess is moderately high (if guess is greater than num) or moderately low (if guess is less than num).

4. If diff is greater than 0 and less than 15, the program outputs the message indicating that the guess is somewhat high (if guess is greater than num) or somewhat low (if guess is less than num).

Give the user no more than five tries to guess the number.

1. (Quadratic Equation) Design a class named QuadraticEquation for a quadratic equation ax2 + bx + c = 0. The class contains:  

• Data fields a, b, and c that represent three coefficients.
• A constructor for the arguments for a, b, and c.
• Three get functions for a, b, and c.
• A function named getDiscriminant() that returns the discriminant, which is b2 - 4ac.
• The functions named getRoot1() and getRoot2() for returning two roots of the equation:

          x₁ = -b + sqrt(b²-4ac) / 2a

x₂ = -b - sqrt(b²-4ac) / 2a

These functions are useful only if the discriminant is non-negative. Let these functions

return 0 if the discriminant is negative.

Write a test program that prompts the user to enter values for a, b, and c, and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display "The equation has no real roots".

Write a program to perform deletion operation on BST. While deleting, consider all the deletion cases. a. Deletion of node with degree 0. b. Deletion of node with degree 1. c. Deletion of node with degree 2.

Note: No global declarations

Call the functions in main through menu

Implement the following :

Singly Linked List with following functions :

1)insert_at_head(node* & head, int val);

2)insert_at_tail(node* & head, int val);

3)display(node* head) ;

4)insert_at_pos(node* & head, int val,int pos);

5)delete_at_head(node* & head);

6)delete_at_tail(node* & head);

7)delete_at_pos(node* & head, int pos);

Write a function to remove the duplicates from the linked list.also give main for the function.

Write a function to check whether given singly linked list is palindrome or not. also give main for the function.
