题目描述
You are given three integers $a$ , $b$ , $k$ .
Find two binary integers $x$ and $y$ ( $x \ge y$ ) such that
1. both $x$ and $y$ consist of $a$ zeroes and $b$ ones;
2. $x - y$ (also written in binary form) has exactly $k$ ones.
You are not allowed to use leading zeros for $x$ and $y$ .

You are not allowed to use leading zeros for $x$ and $y$ .
输入格式
The only line contains three integers $a$ , $b$ , and $k$ ( $0 \leq a$ ; $1 \leq b$ ; $0 \leq k \leq a + b \leq 2 \cdot 10^5$ ) — the number of zeroes, ones, and the number of ones in the result.
输出格式
If it's possible to find two suitable integers, print "Yes" followed by $x$ and $y$ in base-2.
Otherwise print "No".
If there are multiple possible answers, print any of them.
Otherwise print "No".
If there are multiple possible answers, print any of them.

In the first example, $x = 101000_2 = 2^5 + 2^3 = 40_{10}$ , $y = 100001_2 = 2^5 + 2^0 = 33_{10}$ , $40_{10} - 33_{10} = 7_{10} = 2^2 + 2^1 + 2^0 = 111_{2}$ . Hence $x-y$ has $3$ ones in base-2.
In the second example, $x = 10100_2 = 2^4 + 2^2 = 20_{10}$ , $y = 10010_2 = 2^4 + 2^1 = 18$ , $x - y = 20 - 18 = 2_{10} = 10_{2}$ . This is precisely one 1.
In the third example, one may show, that it's impossible to find an answer.
