Ratio By 2

You have $2$ positive integers $X$ and $Y$. In one operation, you can change the value of **one** of the integers by $1$ or $-1$. Find the minimum number of operations needed to ensure that either $X \ge (2 \cdot Y)$ or $Y \ge (2 \cdot X)$, i.e. either $X$ is at least twice as large as $Y$, or $Y$ is at least twice as large as $X$. ### Input - The first line of input will contain a single inte
