___________________________________________________________
Question_1:-

You are given the coefficients of a quadratic equation in order A, B & C.

Where A is the coefficient of X2, B is the coefficient of X and C is the constant term in the most simplified form.

Example: For X2 + 5X + 6 = 0, you are given the input as: 1 5 6.

Write a program to find all of the roots of the quadratic.

Note: The output should be up to 2nd decimal place (round off if needed) and in case of a recurring decimal use braces.

Note: Use Shri Dharacharya's Method to solve i.e. X = {-b + √(b² - 4ac) } / 2a & {-b-√(b² -4ac)} / 2a

Input Description:
Three numbers corresponding to the coefficients of x(squared), x and constant are given as an input in that particular order

Output Description:
Print the two values of X after rounding off to 2 decimal places if required.

Sample Input :
1 5 6
Sample Output :
-2.00
-3.00
**************************
a,b,c = map(int,input().split())
d = ((b**2)-(4*a*c))**0.5
m = (d-b)/(2*a)
n = -(d+b)/(2*a)
print(f'{m:.2f}')
print(f'{n:.2f}')
************************

Question_2:-
Print "Odd" or "Even" for the corresponding cases.

Note: In case of a decimal, Round off to nearest integer and then find the output. Incase the input is zero, print "Zero".

Input Description:
A number is provided as the input.

Output Description:
Find out whether the number is odd or even. Print "Odd" or "Even" for the corresponding cases. Note: In case of a decimal, Round off to nearest integer and then find the output. In case the input is zero, print "Zero".

Sample Input :
2
Sample Output :
Even
*********************
a = int(input())
if a % 2 == 0:
print("Even")
else:
print("Odd")

Question_3:-
Let "A" be a year, write a program to check whether this year is a leap year or not.

Print "Y" if its a leap year and "N" if its a common year.

Input Description:
A Year is the input in the form of a positive integer.

Output Description:
Print "Y" if its a leap year and "N" if its a common year.

Sample Input :
2020
Sample Output :
Y
**********************
A = int(input())
if A%4 == 0:
if A % 1000 == 0:
if A % 400 == 0:
print('Y')
else:
print("N")
else:
print("Y")
else:
print("N")
*********************

Question_4:-
You will be provided with a number. Print the number of days in the month corresponding to that number.

Note: In case the input is February, print 28 days. If the Input is not in valid range print "Error".

Input Description:
The input is in the form of a number.

Output Description:
Find the days in the month corresponding to the input number. Print Error if the input is not in a valid range.

Sample Input :
8
Sample Output :
31
***********************
a = int(input())
b = [1,3,5,7,8,10,12]
c = [4,6,9,11]
d = 2
if a in b:
print(31)
elif a in c:
print(30)
elif a == 2:
print(28)
else:
print('Error')
*********************

Question_5:-
Let "A" be a string. Remove all the whitespaces and find it's length.

Input Description:
A string is provide as an input

Output Description:
Remove all the whitespaces and then print the length of the remaining string.

Sample Input :
Lorem Ipsum
Sample Output :
10
**********************
a = input()
new = ''.join(list1)
print(len(new))
