# Quadratic equation

Write a program to solve a quadratic equation **a**`x`

+ ^{2}**bx** + **c** = **0** (**a** ≠ **0**).

#### Input

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

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.

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
