Problem Statement

Given a string text and regular expression pattern, return true if string text matches with pattern. Otherwise, return false.

Follow the below rules to match text with pattern.

  • '.' matches any single character.
  • '*' matches zero or more occurrences of the preceding element.

Examples

  • Example 1:

    • Input: text = "abc", pattern = "a.c"
    • Expected Output: true
    • Justification: The '.' in the pattern matches any character, so "a.c" matches "abc".

  • Example 2:

    • Input: text = "aadg", pattern = ".*d."
