This is a fully functional PowerShell script I wrote not long ago that converts data (numerical data) among 4 data formats: binary, decimal, hexadecimal and ipv4.
It supports 12 conversions, it can convert number from each type to the other three type, it can convert:
binary to decimal | bi...
I have fully completed my Connect Four project, but the way I checked for a winning position is very repetitive. I feel bad for not being able to find a better solution for this. I have four instances of almost the same code. The only difference is the subtraction and addition signs. Probably eas...

CacheConfig.java
@Configuration
public class CacheConfig {
@Autowired
private AppDao appDao;
@Bean(value = "appCache")

I wrote two template functions to serialize and deserialize structs representing messages to be sent and received via a TCP socket:
/*
* Convert a byte string into a packet.
*/
template <typename PacketType>
PacketType deserialize(std::string &buf, bool partialProcessing = false)
{

I'm working on a mission.
Regarding this mission, the reviewer asked me to change the form to stream, how can I solve this?
public int next(int memberIndex) {
int result = 0;
for(int i = 0; i < last(); i++){
memberIndex = current(i).next(memberIndex);
result = memberIndex;

I'd like to know what is more efficient and performant for the following two cases:
Using conditions before for loops:
if food == 'tomato':
for i in range(1,000,000):
<some logic>
elif food == 'banana':
for i in range(1,000,000):
<some other logic>
OR to use one for loop before th...
I am trying to get a grip on Android UI testing, and from a lot of trying and examples, I figured out this (working test):
@Test
public void FirstScan_ShouldSetSource() {
try(ActivityScenario<ManualMoveActivity> scenario = ActivityScenario.launch(ManualMoveActivity.class)) {

How to refactor many IF statements with multiple conditions like this?
Is there a pattern for this?
if(A == value1 && B == value1) { //do something }
if(A == value1 && B == value2) { //do something }
if(A == value1 && B == value3) { //do something }
if(A == value1 && B == valueN) ...I'm trying to design a chain of responsibility pattern.
It slightly differ from traditional way when handler does only one action on a request, f.e. handles http response considering status code.
But my handlers have to do two actions. Below is an (dummy) example where handler asks a question fir...
