LeetCode Challenge: Goal Parser Interpretation

Description

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"

Constraints

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

Solution:

Steps

1. Declare a output variable, to hold the value of each character match in the command variable
2. Split command variable into an array, then iterate through each character in that array.
3. If we see the character 'G', then add G to the output variable
4. If we see the character '(', the code will then run the nested if statement
5. If there is a ')' character at the following index, then we add 'o' to the output variable
6. If there is are 'a', 'l', and ')' characters in the following 3, index of the command variable then we add 'al' to the output variable
7. When we are done we return the output variable
