Quadratic equation

Task

The program reads the coefficients a, b, c of the quadratic equation ax² + bx + c = 0 (each on its own line, a is not 0) and prints its real roots:

with two roots, both on one line from the smaller to the larger,
with one (double) root, that root,
with no real solution, nema riesenie (no solution).

Two decimal places of precision are enough.

Examples

Input
```
1
-5
6
```
Expected output
```
2 3
```

After you submit, 5 hidden tests will also check your solution: a double root, a negative discriminant, a = 2, irrational roots, a negative a.

Python starts the first time you run code.

a = float(input())
b = float(input())
c = float(input())

Ctrl+Enter runs the program. Tab indents. Press Esc, then Tab, to leave the editor.

Input (stdin)

Each line = one call to input().

Hints

Try it yourself first. Each hint reveals a little more - and lowers the reward a little.

Signed out, hints are free - but no XP is awarded either.

Solution

The solution unlocks after the last hint.
