Given an array of strings patterns and a string word, return the number of strings in patterns that exist as a substring in word.
A substring is a contiguous sequence of characters within a string.
\n\n\n
Example 1:
\n\n\nInput: patterns = ["a","abc","bc","d"], word = "abc"\nOutput: 3\nExplanation:\n- "a" appears as a substring in "abc".\n- "abc" appears as a substring in "abc".\n- "bc" appears as a substring in "abc".\n- "d" does not appear as a substring in "abc".\n3 of the strings in patterns appear as a substring in word.\n\n\n
Example 2:
\n\n\nInput: patterns = ["a","b","c"], word = "aaaaabbbbb"\nOutput: 2\nExplanation:\n- "a" appears as a substring in "aaaaabbbbb".\n- "b" appears as a substring in "aaaaabbbbb".\n- "c" does not appear as a substring in "aaaaabbbbb".\n2 of the strings in patterns appear as a substring in word.\n\n\n
Example 3:
\n\n\nInput: patterns = ["a","a","a"], word = "ab"\nOutput: 3\nExplanation: Each of the patterns appears as a substring in word "ab".\n\n\n
\n
Constraints:
\n\n1 <= patterns.length <= 1001 <= patterns[i].length <= 1001 <= word.length <= 100patterns[i] and word consist of lowercase English letters.给你一个字符串数组 patterns 和一个字符串 word ，统计 patterns 中有多少个字符串是 word 的子字符串。返回字符串数目。
子字符串 是字符串中的一个连续字符序列。
\n\n\n\n
示例 1：
\n\n\n输入：patterns = [\"a\",\"abc\",\"bc\",\"d\"], word = \"abc\"\n输出：3\n解释：\n- \"a\" 是 \"abc\" 的子字符串。\n- \"abc\" 是 \"abc\" 的子字符串。\n- \"bc\" 是 \"abc\" 的子字符串。\n- \"d\" 不是 \"abc\" 的子字符串。\npatterns 中有 3 个字符串作为子字符串出现在 word 中。\n\n\n
示例 2：
\n\n\n输入：patterns = [\"a\",\"b\",\"c\"], word = \"aaaaabbbbb\"\n输出：2\n解释：\n- \"a\" 是 \"aaaaabbbbb\" 的子字符串。\n- \"b\" 是 \"aaaaabbbbb\" 的子字符串。\n- \"c\" 不是 \"aaaaabbbbb\" 的字符串。\npatterns 中有 2 个字符串作为子字符串出现在 word 中。\n\n\n
示例 3：
\n\n\n输入：patterns = [\"a\",\"a\",\"a\"], word = \"ab\"\n输出：3\n解释：patterns 中的每个字符串都作为子字符串出现在 word \"ab\" 中。\n\n\n
\n\n
提示：
\n\n1 <= patterns.length <= 1001 <= patterns[i].length <= 1001 <= word.length <= 100patterns[i] 和 word 由小写英文字母组成word."
