How to generate random values between 00 and FF but without having equal characters combinations?


How to generate random values between 00 and FF but without having equal characters combinations?

fixed the issue. Will look into that further A naïve approach would be simply to try again if you get one of the undesirable values (pseudocode follows):
code :
do
    val = random(0..255)
while val is a multiple of 17
@echo off

rem Get a valid number.
:try
    set /a "xx = %random% %% 256"
    set /a "rem17 = %xx% %% 17"
    if %rem17%==0 goto :try

rem Output it as hex
echo >tmp.vbs WScript.Echo Hex(WScript.Arguments(0))
cscript /nologo tmp.vbs %xx%
del tmp.vbs

I wish this helpful for you Try defining array of numbers which should not be returned , using Array.prototype.indexOf() to filter only numbers between 1 and 10 that are not within array containing 3 , 4, 7
code :
var n = [3, 4, 7];

function rand(not) {
  var r = Math.floor(Math.random() * 10) + 1;
  return not.indexOf(r) === -1 ? r : rand(not)
}

console.log(rand(n))
var n = [1, 2, 5, 6, 8, 9, 10];

function rand(arr) {
  var r = Math.floor(Math.random() * arr.length);
  return arr[r]
}

console.log(rand(n))

hop of those help? The following will create a matrix with first half of numbers less than 0.5 and next half of numbers greater than 0.5 :-
code :
required= [0.5*rand(n,n/2),  0.5+rand(n,n/2)]; 
required=reshape(required(randperm(numel(required))),size(required))

will be helpful for those in need I don't think you can guarantee that each item is picked with the same frequency if you use random.choice. Each choice is equally likely which isn't the same thing.
The best way to do this would be to maintain a list of characters and shuffle it...
code :
characters = C * 8
random.shuffle(characters)
print(''.join(characters))
def get_random_strings(characters, count, N):
    """Yield `N` strings that contain each character in `characters` `count` times."""
    characters = list(characters) * count
    for _ in xrange(N):
        random.shuffle(characters)
        yield ''.join(characters)

To fix this issue The main problem is using tiles_max with a value of 100 in the modulo to get an index into an array of [27]. This simplifies the selection.
code :
//This program is a basic scrabble game with some error checking.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define NUM_LETTERS 7
#define LETTER_SET 27

void generate_letter_set (int letter_set[], int lettersbgood){
    const int tile_set[LETTER_SET] = {9, 2, 2, 4, 12, 2, 3, 2, 9, 1, 1, 4, 2, 6, 8, 2, 1, 6, 4, 6, 4, 2, 2, 1, 2, 1, 2};
    int counter1, chargen;

    counter1 = lettersbgood;
    do {
        chargen = rand() % (LETTER_SET);
        if ( tile_set[chargen] > letter_set[chargen]){
            letter_set[chargen] += 1;
            counter1--;
            printf("%d\n", letter_set[chargen]);
        }
    } while ( counter1);
}

int main()
{
    int counter4;
    int letter_set[LETTER_SET] = {0};

    srand((unsigned) time(NULL));
    printf("This program plays a game of scrabble.\n");
    generate_letter_set(letter_set, NUM_LETTERS);
    printf("Your letters are: \n");
    for(counter4 = 0; counter4 < LETTER_SET; counter4++){
        printf("%d ", letter_set[counter4]);
    }
    printf("\n");
    return 0;
}

Any of those help You can create random values, and then just normalize by the sum of the values.
code :
import random

x = [random.random() for _ in range(4)]
y = [(a / sum(x)) for a in x]
