  2. Here's a way to convert binary numbers to ASCII characters that is often simple enough to do in your head. 1 - Convert every 4 binary digits into one hex digit. Here's a binary to hex conversion chart: 0001 = 1. 0010 = 2. 0011 = 3. 0100 = 4. 0101 = 5. 0110 = 6.

  3. 4. You would only need 5 bits because you are counting to 26 (if we take only upper or lowercase letters). 5 bits will count up to 31, so you've actually got more space than you need. You can't use 4 because that only counts to 15. If you want both upper and lowercase then 6 bits is your answer - 6 bits will happily count to 63, while your ...

  4. How to convert alphabet to binary? - Stack Overflow

    stackoverflow.com/questions/27942881

    Thus, converting the alphabet to binary is dependent on the program in which you are doing so, and outside the context of a program/OS converting the alphabet to binary is really the exact same thing as converting a sequence of numbers to binary, as far as a CPU is concerned.

  5. Arduino 8x8 led matrix letters - Stack Overflow

    stackoverflow.com/questions/55090907

    Below is a sample I put together real quick to demonstrate looping through the alphabet and displaying a letter for a specified amount of time. This code does work, you must connect the 8x8 led matrix inputs to the corresponding pin callouts for the rows and columns in the code provided (or change the code pins to match your connection ...

  6. Use toString(2) to convert to a binary string. For example: var input = document.getElementById("inputDecimal").value; document.getElementById("outputBinary").value = parseInt(input).toString(2); or parseInt(input,10) if you know the input should be decimal. Otherwise input of "0x42" will be parsed as hex rather than decimal.

  7. Binary numbers map one-to-one with decimal numbers, so you can cover a two-character alphabet with binary numbers of length 1, four-characters with length 2, etc. So for a 40-character alphabet you'll need binary codes of length 6. Then if you have them in a list: alphabet = ['A', 'B', 'C', ...] You could get your mapping with

  8. We need to Huffman encode to a binary code alphabet. The source alphabet has four symbols with probabilities: P (A) = 0.4. P (B) = 0.3. P (C) = 0.2. P (D) = 0.1. So for Huffman I take the two symbols with the lowest probability, which are C and D in this example. I construct a subtree with two leaves (C & D). The next symbol in the list, B, has ...

  9. Step-1: When you divide a number ω by n then reminder can be either 0, 1, ..., (n - 2) or (n - 1). If remainder is 0 that means ω is divisible by n otherwise not. So, in my DFA there will be a state q r that would be corresponding to a remainder value r, where 0 <= r <= (n - 1), and total number of states in DFA is n.

  10. Python -- Morse Code Translation through a binary tree

    stackoverflow.com/questions/16161813

    In a high-level language this kind of stuff is already given to you. My advice: learn how to write good idiomatic python on simple but real problems. For example, your morse code decoder - as you correctly pointed out, a lookup table is the best way and will require no more than 5 lines of code. Problem solved, up to the next one. –

  11. I want to make a binary to text converter. I have already made a text to binary converter. Here is the code for that: function convertText() { var output = document.getElementById("binaryConve...
