def compare(p, s):

    lp = len(p)

    i = 0
    j = 0
    while i < lp and j < ls:
        if p[i] == s[j] or p[i] == "?" and s[j].isalnum():
            i += 1
            j += 1

        elif p[i] == "*":
            # 合并**
            while p[i] == "*":
                if i + 1 == lp:
                    return True
                else:

            for k in range(j, ls):

                    return True
            return False

            # 三种情况 匹配0个字符 匹配下一个字符,匹配多个(std不动,还是*在匹配,str下移)
            # return compare(p[i:],s[j:]) or compare(p[i:],s[j+1:]) or compare(p[i:],s[j+1:])

        else:
            return False

    if i == lp and j == ls:
        return True
    else:
        return False


p = input().lower()
s = input().lower()


out = "true" if compare(p, s) else "false"
print(out)
