Replacing Characters of Sentence

You are given a string

S. Write a program to replace each letter of the string with the next letter that comes in the English alphabet.

Note: Ensure that while replacing the letters, uppercase should be replaced with uppercase letters, and lowercase should be replaced with lowercase letters.

Input

The first line of input is a string.

Explanation

In the given example, Hello World.

If we replace each letter with the letter that comes next in the English alphabet,

H becomes I, e becomes f and so on ... So, the output should be Ifmmp Xpsme.

Sample Input 1

Hello World

Sample Output 1

Ifmmp Xpsme

Sample Input 2

Something is better than Nothing

Sample Output 2

Roots of a quadratic equation

You are given coefficients a, b and c of a quadratic equation ax² + bx + c = 0. Find the roots r1, r2 of the equation.

Note:

r1 and r2 should be rounded up to 2 decimal places.Input

The first line of input is an integer a. The second line of input is an integer b. The third line of input is an integer c.

Explanation

In the given example, a = 1, b = -5, c = 6. Then the equation is x² - 5x + 6 = 0

r1 = (-b + (b^2 - 4*a*c)^0.5)/2*a

r1 = (5 + (25 - 24))/2

r1 = 3

and

r2 = (-b - (b^2 - 4*a*c)^0.5)/2*a

r2 = (5 - (25 - 24))/2

r2 = 2

So, the output should be
