About the problem

  • Problem Number : 1678
  • Problem Name : Goal Parser Interpretation
  • Problem difficulty : Easy 🟢
  • Programming language used - Java

Problem

You own a Goal Parser that can interpret a string command. The command consists of an alphabet of "G", "()" and/or "(al)" in some order. The Goal Parser will interpret "G" as the string "G", "()" as the string "o", and "(al)" as the string "al". The interpreted strings are then concatenated in the original order.

Given the string command, return the Goal Parser's interpretation of command.

Example 1:

Input: command = "G()(al)"
Output: "Goal"
Explanation: The Goal Parser interprets the command as follows:
G -> G
() -> o
(al) -> al
The final concatenated result is "Goal".

Example 2:

Input: command = "G()()()()(al)"
Output: "Gooooal"

Example 3:

Input: command = "(al)G(al)()()G"
Output: "alGalooG"

Constraints:

  • 1 <= command.length <= 100
  • command consists of "G", "()", and/or "(al)" in some order.

Approach Explanation

replace method to substitute occurrences of specific patterns in the command string. I replaced "()" with "o" and "(al)" with "al", effectively implementing the interpretation rules of the Goal Parser. This approach simplifies the task of transforming the input string into its interpreted form, providing a concise and readable solution to the problem.
