Table of Contents 🍀

🔥 FULLTIME

Create a table of contents for a simple markup language. It must follow two rules:

If a line starts with a single # followed by a space, then it's a chapter title.

If a line starts with a double # followed by a space, then it's a section title.

The table of contents should be displayed in the following format:

Note that each number is followed by a period and the last period is followed by 1 space.

Function Description

Complete the function tableOfContents in the editor.

tableOfContents has the following parameter:

string text[n]: the input text

Returns

string[]: each string is a line in the table of contents

Example 1:

Input:  text = ["# Cars", "Cars came into global use during the 20th century", "Most definitions of car say they run primarily on roads", "## Sedan", "Sedan's first recorded use as a name for a car body was in 1912", "## Coupe", "Coupe is a passenger car with a sloping rear roofline and generally two doors", "## SUV", "The predecessors to SUVs date back to military and low-volume models from the late 1930s", "There is no commonly agreed definition of an SUV, and usage varies between countries."]
Output: ["1. Cars", "1.1. Sedan", "1.2. Coupe", "1.3. SUV"] 
Explanation:
The first line of input indicates there are n = 10 lines of text. There is only 1 chapter in the input, and it contains 3 sections. All the lines that don't begin with # or ## are ignored in the table of contents.

Constraints:

1 ≤ n ≤ 1000

1 ≤ length of text[i] ≤ 100

When a line starts with # or with ##, these special characters are always followed by a space.

The first line of the text is guaranteed to be a chapter line.
