At its core, a sorting algorithm orders the elements of a list based on a certain attribute. This could be numerical value, alphabetical order, or any other property that has a defined order. The efficiency of a sorting algorithm is typically measured in terms of its time complexity, which ...

Also, try to avoid java.util.Stack for reasons you don't yet understand (think "it's old"). Use a Deque interface and a ArrayDeque (preferred) or LinkedList implementation. Deque<String> stack = new ArrayDeque<>(); When done with this, instead of your old while (Stack.size() > ...
While ArrayList is a powerful tool, it’s not always the best choice. Other data structures, such as LinkedList and Array, might be more suitable depending on the situation. ArrayList vs LinkedList: Both are part of the Java Collections Framework and can store elements dynamically. However, Arr...
