Find the Third Largest Number in a List

To implement a program that Find the third largest number in a list.

To find the third largest number in a list, used a straightforward approach that sorting the list in ascending order and then accessing the element at the index corresponding to the third largest position.

- Start with a list of numbers.
- Sort the list in ascending order. There are various sorting algorithms available, such as bubble sort, insertion sort, selection sort, merge sort, and quicksort. Choose an appropriate sorting algorithm. In Python, you can use the built-in sort() method to sort the list in ascending order. Python uses Timsort in its sort() method.
- After sorting the list, the third largest number will be at index third-to-last. Access the element at this index to obtain the third largest number.
- If the list has fewer than three elements, it may not have a third largest number. In such cases, you can either handle it as an error condition or consider it a special case based on the requirements of your application.

- To understand how to initialize an empty list in Python and use a loop construct to iterate and input elements into the list.
- List manipulation: You will learn how to manipulate lists in Python, including adding elements, sorting, and accessing elements at specific indices. This knowledge is essential for working with collections of data in Python.
- Indexing and accessing elements: By accessing the third largest number in the list using its index, you will reinforce your understanding of indexing in Python. You'll also learn how to handle edge cases when the list has fewer than three elements.
