1967. Number of Strings That Appear as Substrings in Word
Description
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 = "abc" Output: 3 Explanation: - "a" appears as a substring in "abc". - "abc" appears as a substring in "abc". - "bc" appears as a substring in "abc". - "d" does not appear as a substring in "abc". 3 of the strings in patterns appear as a substring in word.
Example 2:
Input: patterns = ["a","b","c"], word = "aaaaabbbbb" Output: 2 Explanation: - "a" appears as a substring in "aaaaabbbbb". - "b" appears as a substring in "aaaaabbbbb". - "c" does not appear as a substring in "aaaaabbbbb". 2 of the strings in patterns appear as a substring in word.
Example 3:
Input: patterns = ["a","a","a"], word = "ab" Output: 3 Explanation: Each of the patterns appears as a substring in word "ab".
Constraints:
1 <= patterns.length <= 100
1 <= patterns[i].length <= 100
1 <= word.length <= 100
patterns[i]
andword
consist of lowercase English letters.
