there are lot similar questions out there. However, I wanted to ask to comment on my code. My implementation (as i believe) is fairly simple than the other complex ones. It has O(2) complexity.
My approach is simple

I'm stuck on this problem. The whole code got ugly quickly, and the solution below did not work. Here is how I tried to solve quick sort:

I tried to created a Tree like Network that take info from a text file and create a Tree like Network topology.

This here is some fairly simple functionality
The user has a list of objects, which they modify, or may create a new object.
When the user presses 'Save/Update' the 'saveClick()' function is called.
This will submit the object to the backend. If it's a new object, the backend will generate a u...
This trait is meant to be a simple interface for tabular data from different file types, such as csv, excel, open office etc. Right now I'm only asking about some of the top level code for now and not the implementations. I'm worried that I might have made some poor design choices. But first l...

Using Java 1.8, I created the following implementation to concat two int arrays:
public static int[] concat(int[] array1, int[] array2) {
return IntStream.concat(Arrays.stream(array1), Arrays.stream(array2)).toArray();
}
The unit test I created to test this looks like this:

I solved the bubble sort in exam.
the code is below,

var temp = undefined,isSwap = false;
for(var x = 0; x < myArray.length; x++){

temp = myArray[x];
myArray[x] = myArray[x+1];
