Quadratic equation

Quadratic equation

Time limit 1 second
Memory limit 128 MiB

Solve a quadratic equation a \cdot x^2 + b \cdot x + c = 0~(a \ne 0).

Input data

One line contains 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" if there are no roots. If equation contains only one root, print "One root:", space and a root. In the case of two roots, print "Two roots:", space, first smaller, and then larger root. It is guaranteed that if the roots exist, they are integers.
