3407: Substring Matching Pattern

Problem Statement

You are given a string s and a pattern string p, where p contains exactly one '*' character.

The '*' in p can be replaced with any sequence of zero or more characters.

Return true if p can be made a substring of s, and false otherwise.

Example 1:

Input: s = "leetcode", p = "ee*e"

Output: true

Explanation:

By replacing the '*' with "tcod", the substring "eetcode" matches the pattern.

Example 2:

Input: s = "car", p = "c*v"

Output: false

Explanation:

There is no substring matching the pattern.

Example 3:

Input: s = "luck", p = "u*"

Output: true

Explanation:

The substrings "u", "uc", and "uck" match the pattern.

Constraints:

  • 1 <= s.length <= 50
  • 1 <= p.length <= 50
  • s contains only lowercase English letters.
  • p contains only lowercase English letters and exactly one '*'
