Evaluate two sorting or two search algorithms : Selection sort demonstration and complexity analysis

The video tutorial explains the selection sort algorithm, which sorts a list by repeatedly finding the smallest element and moving it to the beginning. The process involves using a spot marker to track sorted sections and iterating through the list to perform swaps. The video also covers the complexity of the algorithm, which is O(n^2), and encourages viewers to implement the algorithm in Python.

What is the main idea behind the selection sort algorithm?

How does selection sort differ from bubble sort in terms of sorting direction?

Describe the process of the first iteration in the selection sort algorithm.

What happens to the spot marker after each iteration in selection sort?

How can you visualize the sorted and unsorted parts of the list during the selection sort process?

Explain why the complexity of selection sort is considered O(N^2).

What is the significance of dropping lower order terms when analyzing algorithm complexity?
