Problem Description

Xiaoshan and Xiaoxi share an apartment and need to split the monthly water bill together. The water bill uses a tiered pricing system with the following rules:

1. For the portion of total monthly water usage not exceeding $10$ cubic meters (including $10$ cubic meters), the rate is $4$ yuan per cubic meter.
2. For the portion of total monthly water usage exceeding $10$ cubic meters, the rate is $5$ yuan per cubic meter.

Xiaoshan uses $a$ cubic meters of water per month, and Xiaoxi uses $b$ cubic meters of water per month.

They have agreed on a set of rules for splitting the total cost:

1. If the total water usage does not exceed $10$ cubic meters, they split the cost equally.
2. If the total water usage exceeds $10$ cubic meters, the cost for the first $10$ cubic meters is split equally, and the cost for the portion exceeding $10$ cubic meters is paid entirely by the person who uses more water (either $a$ or $b$).

Input Format

A single line containing two integers $a$ and $b$, representing the water usage contributed by Xiaoshan and Xiaoxi respectively (in cubic meters). It is guaranteed that $a$ is not equal to $b$.

Output Format

A single line containing two integers separated by a space, representing the final water bill amounts that Xiaoshan and Xiaoxi should pay respectively (in CNY).

Hint

[Sample $1$ Explanation]

$5+4<10$, therefore they split the bill equally.

Total bill: $(5+4)\times 4 = 36$, Split equally, so each person pays $18$ yuan.

[Sample $2$ Explanation]

$5+6>10$, therefore they do not split the bill equally.

For the first $10$ cubic meters: $(5+5)\times 4 = 40$;

For the portion exceeding $10$ cubic meters: $(5+6-10)\times 5 = 5$;

They split the $40$ equally, and the remaining portion is paid by Xiaoxi. Therefore, Xiaoshan pays $20$ yuan, and Xiaoxi pays $25$ yuan.

[Constraints]

For $30\%$ of the test cases, $0 \le a, b \le 5$.

For another $30\%$ of the test cases, $5 < a, b \le 20$.

For $100\%$ of the test cases, $0 \le a, b \le 20$, and $a \neq b$.
