From 0 to 1 Data Structures & Algorithms in Java - Selection Sort

The video introduces selection sort, a simple sorting algorithm. It explains the process of selecting the smallest element in each iteration and placing it at the beginning of the list. An example with a ten-element array is provided to illustrate the steps. The video also covers the Java code implementation and discusses the algorithm's characteristics, including its time complexity, stability, and space usage. Selection sort is noted for its simplicity but is not efficient for large datasets.

How does selection sort determine the smallest element in the list?

Explain the process of swapping elements in selection sort.

What happens to the first element after the first iteration of selection sort?

Describe the overall process of selection sort from start to finish.

What is the role of helper methods in implementing selection sort?

What is the time complexity of selection sort and why?

Discuss the stability of selection sort. Is it stable or unstable?

How does selection sort handle nearly sorted lists?

What are the advantages and disadvantages of using selection sort?
