Codewars: Find the odd int
Tags: javascript, codewars, leetcode, teaching
Published: 2024-03-26 08:36:10

**This problem on codewars asks the following:**

Given an array, find the integer that appears an odd number of times. There will always be exactly one integer that appears an odd number of times.

**Example:** `(Input --> Output)`

```js
findOdd([20, 1, 1, 2, 2]) = 20
findOdd([5, 4, 3, 2, 1, 5, 4, 3, 2, 10, 10]) = 1
```

How to approach it with the PEDAC method:

<u>**P:** Understand the problem - </u>
We need to identify which number in an array appears an odd number of times. Although each number can appear multiple times, only one will appear an odd number of times.

<u>**E:** Give Example -</u>
In an array like [8, 8, 7, 7, 7], 7 shows up 3 times (odd), making it our target.
For [1, 1, 2], 2 appears just once (odd), pinpointing it as the solution.

<u>**D:** What data structure(s) would be needed - </u>
An object seems perfect for mapping each number to its occurrence count within the array.

<u>**A:** Steps to solve it without language specific information - </u>

**- Loop first through the array:** This allows me to inspect each number individually.

**- If I arrive at a number, add it to a data structure: object** 

**- Check if the number has been encountered before. If not, initialize its count in the object. If the number is already in the object, increment its count**

**- Loop through the object to inspect counts and return the odd number of counts** 

<u>**C:** Code the solution guided by the pseudocode- </u>

**- Loop first through the array**
```javascript
for (let i of A) {
```

**- If I arrive at a number, add it to a data structure: object**
**- Check if the number has been encountered before. If not, initialize its count in the object. If the number is already in the object, increment its count**
```javascript
  if (!values[i]) {
    values[i] = 1;
  } else {
    values[i] += 1;
  }
}
```

**- Loop through the object to inspect counts and return the odd number of counts**
```javascript
for (let k in values) {
  if (values[k] % 2 === 1) {
    return Number(k);
  }
}
```

Putting it all together in the function `findOdd`:

```javascript
function findOdd(A) {
  let values = {};
  
  // Loop first through the array
  for (let i of A) {
    // Check if the number has been encountered before
    if (!values[i]) {
      values[i] = 1; // If not, initialize its count
    } else {
      values[i] += 1; // If it has, increment its count
    }
  }
  
  // Loop through the object to find and return the number with an odd count
  for (let k in values) {
    if (values[k] % 2 === 1) {
      return Number(k);
    }
  }
}
```

Java FTPS disabling Certificate Check , FOR FIX FTP SSL certificate expired exception
Tags: java, sftp
Published: 2024-03-26 08:00:02

1)the encryption of the FTPS server will be either TLS explicit encryption or TLS explicit encryption.Use the constructor arg for FTPS accordingly. like

```
FTPSClient ftpClient = new FTPSClient(false);
```


2)if your FTPS server security certificate has expired, disable the check from client by

```
ftpClient.setTrustManager(new X509TrustManager() {
    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    @Override
    public void checkClientTrusted(X509Certificate[] certs, String authType) {
    }

    @Override
    public void checkServerTrusted(X509Certificate[] certs, String authType) {
    }
});
```


3)enable file transfer between server and client using this method

```
ftpClient.enterLocalPassiveMode();
```


4)use the right port number. Usually for explicit encryption it is 21 and for implicit it is 990

The above four are the common configs required to establish a connection. The end snippet looks something like this

```

FTPSClient ftpClient = new FTPSClient(false);
        ftpClient.setTrustManager(new X509TrustManager() {
            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }

            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }

            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        });
        ftpClient.connect("ftps.mydomain.com",21);
        boolean res = ftpClient.login("username", "password");
        if(!res) throw new Exception("unable to connect to ftps");
        int reply=ftpClient.getReplyCode();
        if(FTPReply.isPositiveCompletion(reply)){
            ftpClient.enterLocalPassiveMode();
            FTPFile[] ftpFiles = ftpClient.listFiles("/folder/subfolder");
            System.out.println("complete "+reply+" "+ftpFiles.length);
            for(FTPFile x: ftpFiles){
                System.out.println(x.getName());
            }
            ftpClient.retrieveFile("/folder/subfolder/file.tsv",new FileOutputStream(new File("C:\\Users\\myname\\Desktop\\out.csv")));
        }else{
            throw new RuntimeException("unable to get valid reply from ftp server. Reply code is "+reply);

Assessing the usability of user interfaces in software systems
Published: 2024-03-26 07:24:43

**** Assessing the usability of user interfaces in software systems

Creating software systems with usable interfaces is a key aspect of successful software development. But it requires careful analysis and evaluation of interface usability. The following is a five-step guide to evaluating the usability of user interfaces in software systems.

**Step 1: Determine usability metrics**

Before you can begin evaluating the usability of your interface, you need to identify key usability metrics. These metrics include learnability (how easy it is to learn the system), efficiency (how quickly a task is completed), memorability (users' ability to remember and recall their actions), errors (frequency and severity of user errors), and satisfaction (user satisfaction with using the interface).

Step 2: User Testing

After defining the metrics, the next step is to develop user testing scenarios. These scenarios should reflect typical tasks that users will perform when using the software system. Test participants representing the target audience should be observed as they interact with the interface.

Stage three: data collection

Data collection included quantitative and qualitative analyses. Quantitative data can be collected using task completion rates and task completion times. Qualitative data can be collected by observing users and their feedback on the interaction of the interface.


Step 4: Usability Analysis

Once the data has been collected, you can start analysing the usability of your interface. This analysis will help you identify problem areas, pain points, and areas for usability improvement. For example, high error rates or long task completion times may indicate that you need to rethink your interface design.

Step 5: Suggestions

Based on the results of the analysis, recommendations are developed to improve the usability of the interface. This may include redesigning the layout, improving the navigation structure, adding tooltips, or incorporating user feedback mechanisms.

In general, evaluating the usability of user interfaces in software systems requires a systematic approach that begins with identifying metrics and ends with developing recommendations for improvements. A properly performed evaluation will result in a software system that is successfully adopted and used by end users.

Know In Quite A Detail How Wisdom Teeth Removal Works And How Important It Is
Published: 2024-03-26 07:17:00

Wisdom teeth, occasionally referred to as third molars, generally erupt between 17 and 25. If these teeth erupt efficiently and line up with the relaxation of your teeth, they may be considerable assets. But most of the time, they bring problems that require their removal. To maintain first-class, feasible dental fitness, understanding the process of [wisdom teeth removal](https://peninsulaofs.com/procedures/wisdom-teeth-removal/) and its importance is crucial.

**The Need for Wisdom Teeth Removal**

**Impaction***

Impaction is a major thing in know-how enamel extractions. Because of the jaw's restrained space, these teeth may develop at atypical angles or end up stuck beneath the gum line, resulting in pain, swelling, and infection.

**Crowding**

The wisdom tooth can crowd and misalign neighboring teeth by applying pressure. This may cause your orthodontic techniques to grow to be misaligned, in which case their removal will be essential to preserve the integrity of your smile.

**Infection**

The danger of infection, gum ailment, and rot will increase while third molars that have erupted in part create spaces where bacteria can develop—[wisdom tooth extractions](https://peninsulaofs.com/procedures/wisdom-teeth-removal/) aid in stopping those troubles with dental health.

**The wisdom teeth removal process**

**Consultation**
Your oral surgeon or dentist will take a look at your oral health, attain X-rays to decide the position of your wisdom enamel, and determine if extraction is needed.

**Anesthesia**

Anesthesia may be administered t to guarantee your comfort and no pain for the entire procedure. You might be given general, sedative, or local anesthesia, depending on how complex the extraction is and what you want.

**Extraction**

The extraction will then be performed with the aid of an oral general practitioner or dentist. They will reduce the hole within the gum tissue, eliminate any bone preventing the tooth from being reachable, and cast off the wisdom teeth. 

**Closure**

After the tooth is eliminated, the surgical location might need to be sutured to prevent bleeding and facilitate recovery.

**Post-Extraction Care**

Medications, over-the-counter pain relievers, and cold compresses can all help to alleviate discomfort and swelling.

Limit your diet to liquids and soft meals at first, then gradually resume solid foods as you heal. Eat nothing that might irritate the surgical operation area, together with hard, crunchy, or spicy foods.
Maintaining top dental hygiene is important to keeping off infections and inspiring healing.
Follow-up appointments make sure everything is well by keeping track of your recovery.

**Conclusion**

Wisdom teeth removal is a preferred dental operation to maintain oral health and avoid further troubles. Do not hesitate to speak about your remedy options with the Peninsula Oral and Facial Surgery dentist if you are having symptoms related to your understanding of enamel.
