Background

I originally planned to make it harder, but never mind.

Problem Description

Given an organic compound containing only $\text{C, H, O}$ elements, output the coefficients of $\mathrm{CO_2}$ and $\mathrm{H_2O}$ in the balanced chemical equation for its reaction with oxygen.

Input Format

One line, a string representing the organic compound.

Output Format

Two numbers, which are the coefficients of $\mathrm{CO_2}$ and $\mathrm{H_2O}$, respectively.

C2H5OH

2 3

Hint

Sample explanation:

$$\mathrm{C_2H_5OH + 3 O_2 \xlongequal{\text{点燃}} 2 CO_2 + 3 H_2O}$$

---

For $100\%$ of the testdata:

• The string length does not exceed $10$.
• The coefficients of $\mathrm{CO_2}$ and $\mathrm{H_2O}$ to be found do not exceed $400$.
• The given organic compound is valid and contains only $\text{C, H, O}$ elements.
