Random word12/26/2023 Yet even using only common English words, there are still plenty to go around. According to some scholars, there are more than a million English words. So “” would be considered a different ordered triple than “.” In fact, in the what3words system, is in fact on a mountain in Alaska, not in the middle of the RIT Tigers Turf Field, like .įinding out how many words are used in a language and whether there are enough ordered triples to map the entire world are the next steps. Dividing 510 trillion by 9 reveals that uniquely identifying each square on Earth requires around 57 trillion ordered triples of three random words.Īn ordered triple is just a list of three things in which the order matters. Therefore, working in the metric system, Earth’s surface area is equivalent to 510 trillion square meters. Remember: What3words is using 3-meter-by-3-meter squares, each of which contains 9 square meters of surface area. With r = 3,959 (6,371), this works out to approximately 197 million square miles (510 million square kilometers). To compute the surface area of the Earth, use the formula 4πr 2. Start with the basic assumption that the Earth is a sphere, recognizing that this is an approximate truth, and that its radius is approximately 3,959 miles (6,371 kilometers). Here’s how three random words in English or any other language can identify such precise locations across the entire planet.

Because of this, the system is well suited for emergency services. In addition, three words are easier for humans to remember and communicate to one another than, say, detailed latitude and longitude measurements. First, it’s more precise than regular street addresses. This new approach to geocoding is quite useful for several reasons. As an example, there’s a square in the middle of the Rochester Institute of Technology Tigers Turf Field coded to. So, you could think of them as approximately 10-foot-by-10-foot squares, which is about the size of a small home office or bedroom. If your brain operates more naturally in the Imperial measurement system, 3 meters is about 9.8 feet. What3words is an app and web-based service that provides a geographic reference for every 3-meter-by-3-meter square on Earth using three random words. The secret behind this amazing power is just a little bit of math. It’s difficult to imagine that three random words have the power to both map the globe and protect your private data. If (rand.The math of threes is surprisingly powerful. Throw new ArgumentException("Length must be greater than 0") If (length < 1) // do not allow words of zero length Try this method: string GenerateWord(int length) However, when a Q is encountered, the loop adds 3 characters, which causes the loop to execute one additional time, and you end up with one extra character. You use two separate loops, depending on whether the length is even or odd, and assume in each that the loop will add two characters. Your problem is occurring because of the way you are constructing your loops. Private static string GetRandomLetter(Random rnd, string letters) Word = word.Replace("q", "qu").Substring(0, requestedLength) // We may generate a string longer than requested length, but it doesn't matter if cut off the excess. Word += GetRandomLetter(rnd, consonants) + GetRandomLetter(rnd, vowels) String consonant = new string įor (int i = 0 i < requestedLength i+=2) Here is the code: public void WordFinder() I have marked my problem area with a star in the comment above it. My only issue is that I told it to add a "u" to the letter sequence if a "q" shows up right before it, but no matter what I've done it makes the word at least 1 letter too long. The algorithm adds a consonant and then a vowel for each consecutive letter in the sequence, which isn't ideal, but works well enough for basic words. It generates a word based on the length defined by the user. So I made a pretty simple word generator program in c# that works relatively well.
