# Quadratic equation

Write a program to solve a quadratic equation a`x^2`

+ bx + c = 0 (a ≠ 0).

## Input data

Three integers - the coefficients of quadratic equation are given in one line: a, b and c. The values of coefficients do not exceed 100 by absolute value.

## Output data

Print in one line the message "No roots" (without quotes) if there is no roots. If equation contains only one root, print "One root:" (without quotes), space and a root. In the case of two roots, print "Two roots:" (without quotes), space, first smaller, and then larger root. It is guaranteed that if the roots exist, they are integers.

## Examples

Input example #1

1 -5 6

Output example #1

Two roots: 2 3

Input example #2

1 5 6

Output example #2

Two roots: -3 -2
