# PP1 and Competitive Programming

Write a program to solve a quadratic equation ax2 + bx + c = 0 (a0).

#### 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.
