There is a string $S$ consisting of digits `1`, `2`, $...$, `9`. Lunlun, the Dachshund, will take out three consecutive digits from $S$, treat them as a single integer $X$ and bring it to her master. (She cannot rearrange the digits.) The master's favorite number is $753$. The closer to this number, the better. What is the minimum possible (absolute) difference between $X$ and $753$? ## Constraints * $S$ is a string of length between $4$ and $10$ (inclusive). * Each character in $S$ is `1`, `2`, $...$, or `9`. ## Input Input is given from Standard Input in the following format: $S$ [samples]

Samples

Input #1

1234567876

Output #1

34

Taking out the seventh to ninth characters results in $X = 787$, and the difference between this and $753$ is $787 - 753 = 34$. The difference cannot be made smaller, no matter where $X$ is taken from.
Note that the digits cannot be rearranged. For example, taking out `567` and rearranging it to `765` is not allowed.
We cannot take out three digits that are not consecutive from $S$, either. For example, taking out the seventh digit `7`, the ninth digit `7` and the tenth digit `6` to obtain `776` is not allowed.

Input #2

Output #2

0

If `753` itself can be taken out, the answer is $0$.

Input #3

1111111111

Output #3

642

No matter where $X$ is taken from, $X = 111$, with the difference $753 - 111 = 642$.
