Optimized Recursive Coding Challenge | Dataford Interview Questions

Tell me about solving a recursive coding challenge that requires optimized time and space complexity.

Implement is_match(s, p) to determine whether the entire string s matches pattern p, where . matches any single character and * matches zero or more occurrences of the preceding element. Use recursion with memoization and return a boolean.

Constraints

0 <= len(s) <= 200
0 <= len(p) <= 200
s contains lowercase English letters
p contains lowercase English letters, . and *
* always follows a valid preceding pattern element
The match must consume the entire string and pattern

Function Signature

def is_match(s, p):
