I am attempting to solve this code in order to determine the name associated with the array below:
let numbers=[42,67,74,62,6A,1F,58,64,60,66,64,71];
for(let i=0;i<numbers.length;i++)
{
numbers[i] = numbers[i]+1;
}
Any guesses on what the resulting output will be?
Thank you
The original array provided is invalid as it contains hexadecimal numbers like 6A and 1F which are not recognized in JavaScript. To fix this, all the numbers in the array need to be preceded by 0x for them to be treated as hexadecimal numbers (as opposed to base10 numbers). Let's correct the array first:
let name = [0x42,0x67,0x74,0x62,0x6A,0x1F,0x58,0x64,0x60,0x66,0x64,0x71];
Alternatively, we could have used strings and converted them to hexadecimal (base16) numbers:
let name = ['42','67','74','62','6A','1F','58','64','60','66','64','71'].map(n => parseInt(n, 16));
With the corrected array, we can now use String.fromCharCode to decipher the message in the array:
name.map(String.fromCharCode).join('')
However, the meaning of the decoded message is still unclear...
Are you looking for something like this?
let letters = [42,67,74,62,0x6A,0x1F,58,64,60,66,64,71];
var word = "";
for(let i=0;i<letters.length;i++)
{
word+=String.fromCharCode(letters[i]);
}
console.log(word);Or perhaps:
let letters = [42,67,74,62,0x6A,0x1F,58,64,60,66,64,71];
console.log(String.fromCharCode(...letters));*Please note that your values are in hexadecimal base and should be specified by adding 0x
Due to the ambiguity of the base representation of the numbers and the lack of information in the hex output, a trial and error approach is taken. Bases are tested from 2 to 30 to check if any valid output can be obtained.
Please note: The removal of non-printable ASCII characters is done using the regular expression
/[^ -~]+/g
Instead of resorting to JavaScript, there are numerous online decoder tools available such as . By entering the input and decoding it through these tools, multiple interpretations can be obtained. This method proves to be more efficient than using JavaScript to extract a meaningful word from the input.
let name = ['42','67','74','62','6A','1F','58','64','60','66','64','71'];
const ob = {};
for(let i = 2; i <= 30; i++){
let temp = name.map(x => parseInt(x, i));
// Removing non-printable ASCII Characters
let tempRes = String.fromCharCode(...temp).replace(/[^ -~]+/g, "");
ob[`Base${i}`] = tempRes;
}
console.log(ob);I'm a newcomer to the world of web development and I have an idea to make stars move across my website. However, I'm concerned about whether this might be too much for a simple website to handle. Is there a way to optimize the code? const canvas ...
