You are given two strings $S$ and $T$ consisting of lowercase English letters. Determine if there exists a pair of integers $c$ and $w$ such that $1 \leq c \leq w < |S|$ and the following condition is satisfied. Here, $|S|$ denotes the length of the string $S$. Note that $w$ must be **less than** $|S|$. * If $S$ is split at every $w$ characters from the beginning, the concatenation of the $c$\-th characters of the substrings of length at least $c$ in order equals $T$. ## Constraints * $S$ and $T$ are strings consisting of lowercase English letters. * $1 \leq |T|$ $\leq $ $|S| \leq 100$ ## Input The input is given from Standard Input in the following format: $S$ $T$ [samples]

Samples

Input #1

atcoder toe

Output #1

Yes

If $S$ is split at every two characters, it looks like this:

at
co
de
r

Then, the concatenation of the 2nd characters of the substrings of length at least $2$ is `toe`, which equals $T$. Thus, print `Yes`.

Input #2

beginner r

Output #2

No

$w=|S|$ is not allowed, and no pair of integers $1 \leq c \leq w < |S|$ satisfies the condition. Thus, print `No`.

Input #3

verticalreading agh

Output #3

No
