You are given two strings s and t. The string s consists of lowercase Latin letters and at most one wildcard character '*', the string t consists only of lowercase Latin letters. The length of the string s equals n, the length of the string t equals m.

The wildcard character '*' in the string s (if any) can be replaced with an arbitrary sequence (possibly empty) of lowercase Latin letters. No other character of s can be replaced with anything. If it is possible to replace a wildcard character '*' in s to obtain a string t, then the string t matches the pattern s.

For example, if s="aba*aba" then the following strings match it "abaaba", "abacaba" and "abazzzaba", but the following strings do not match: "ababa", "abcaaba", "codeforces", "aba1aba", "aba?aba".

If the given string t matches the given string s, print "YES", otherwise print "NO".

Input

The first line contains two integers n and m (1 ≤ n, m ≤ 2 ⋅ 10^5) — the length of the string s and the length of the string t, respectively.

The second line contains string s of length n, which consists of lowercase Latin letters and at most one wildcard character '*'.

The third line contains string t of length m, which consists only of lowercase Latin letters.

Output

Print "YES" (without quotes), if you can obtain the string t from the string s. Otherwise print "NO" (without quotes).

Examples

Input

6 10
code*s
codeforces


Output

YES


Input

6 5
vk*cup
vkcup


Output

YES


Input

1 1
v
k


Output

NO


Input

9 6
gfgf*gfgf
gfgfgf


Output

NO

Note

In the first example a wildcard character '*' can be replaced with a string "force". So the string s after this replacement is "codeforces" and the answer is "YES".

In the second example a wildcard character '*' can be replaced with an empty string. So the string s after this replacement is "vkcup" and the answer is "YES".

There is no wildcard character '*' in the third example and the strings "v" and "k" are different so the answer is "NO".

In the fourth example there is no such replacement of a wildcard character '*' that you can obtain the string t so the answer is "NO".
