Timur loves codeforces. That's why he has a string $s$ having length $10$ made containing only lowercase Latin letters. Timur wants to know how many indices string $s$ differs from the string "codeforces".

For example string $s =$ "coolforsez" differs from "codeforces" in $4$ indices, shown in bold.

Help Timur by finding the number of indices where string $s$ differs from "codeforces".

Note that you can't reorder the characters in the string $s$.

Input

The first line contains a single integer $t$ ($1 \leq t \leq 1000$) — the number of test cases.

Each test case is one line and contains the string $s$, consisting of exactly $10$ lowercase Latin characters.

Output

For each test case, output a single integer — the number of indices where string $s$ differs.
