You are given an array of positive integers arr. Perform some operations (possibly none) on arr so that it satisfies these conditions:

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。   示例 1： 输入：patterns = ["a","abc","bc","d"], word = "abc" 输出：3 解释： - "a" 是 "abc" 的子字符串。 - "abc" 是 "abc" 的子字符串。 - "bc" 是 "abc" 的子字符串。 - "d" 不是 "abc" 的子字符串。 patterns…

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.   Example 1: Input: patterns = ["a","abc","bc","d"], word…
