# Pattern Matching

1. You are given a string and a pattern. 2. You've to check if the string is of the same structure as pattern without using any regular expressions. Note -> Check out the question video and write the recursive code as it is intended without changing signature. The judge can't force you but intends you to teach a concept.

# Pattern Matching

medium

1. You are given a string and a pattern. 2. You've to check if the string is of the same structure as pattern without using any regular expressions. Note -> Check out the question video and write the recursive code as it is intended without changing signature. The judge can't force you but intends you to teach a concept.

## Constraints

1 <= length of str,ptr <= 20

## Format

### Input

A String str A pattern ptr

### Output

Check the sample ouput and question video.

## Example

Sample Input

```.css-23h8hz{color:inherit;font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;}graphtreesgraph pep```

### Sample Output

```.css-3oaykw{color:var(--chakra-colors-active-primary);font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;font-family:Monospace;}p -> graph, e -> trees, . ```
