math - C#: Dice Permutation without Repetition -


how can change c# code below list possible permutations without repetitions? example: result of 2 dice rolls produce 1,1,2 means 2,1,1 should not appear.

below code:

string[] permutate(int input) { string[] dice; int numberofdice = input; const int diceface = 6; dice = new string[(int)math.pow(diceface, numberofdice)]; int indexnumber = (int)math.pow(diceface, numberofdice); int range = (int)math.pow(diceface, numberofdice) / 6; int dicenumber = 1; int counter = 0; (int = 1; <= indexnumber; i++) { if (range != 0) { dice[i - 1] += dicenumber + " "; counter++; if (counter == range) { counter = 0; dicenumber++; } if (i == indexnumber) { range /= 6; = 0; } if (dicenumber == 7) { dicenumber = 1; } } thread.sleep(1); } return dice; }

the simplest possible way think of:

list<string> dices = new list<string>(); (int = 1; <= 6; i++) { (int j = i; j <= 6; j++) { (int k = j; k <= 6; k++) { dices.add(string.format("{0} {1} {2}", i, j, k)); } } }

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
