# Math/Statistics - All possible combinations of a survey's answers :(

## Recommended Posts

Hi,

I've this topic which deals with something similar but not exactly the same... As my question is a bit more difficult...

I'd like to know how to get all the possible answer results of a an online survey.

Ex:

Question1 - 1/2/3

Question2 - 1/2

Question3 - 1/2

All possible permutations of the above survey will be 3*2*2 (12) that i know...

What I need is to output all the possible results into a table...

Ex:

__________________

1,1,1 | 2,1,1 | 3,1,1 |

1,1,2 | 2,1,2 | 3,1,2 |

1,2,1 | 2,2,1 | 3,2,1 |

1,2,2 | 2,2,2 | 3,2,2 |

I know i should use some recursive method for that... any idea ?!

Any help will be appreciated.

SK.

This is more of a math problem, should be in chat.

No it shouldn't ... the math problem is not even there ... The issue is how to loop through and create the proper output !

Code:

```;Number of rows = Number of questions
Dim \$aQuestions[3]

;Assign each question a number of possible answers
\$aQuestions[0] = 3
\$aQuestions[1] = 2
\$aQuestions[2] = 2

_Recurse(\$aQuestions)

Func _Recurse(ByRef \$aArray, \$iIndex=0, \$sString ='')
For \$Y = 1 to \$aArray[\$iIndex]
\$newString = \$sString & \$Y

;Dump line at deepest recursion depth
If \$iIndex = Ubound(\$aArray)-1 Then
ConsoleWrite(\$newString & @CRLF)
Else
\$newString &= ','
_Recurse(\$aArray, \$iIndex+1, \$newString)
EndIf
Next
EndFunc```

Output:

```1,1,1
1,1,2
1,2,1
1,2,2
2,1,1
2,1,2
2,2,1
2,2,2
3,1,1
3,1,2
3,2,1
3,2,2```

Well... solved it already... forgot to update in here as i was needing it for a PHP project i'm working on ...

here is what i came up with:

```\$rules = 1; // At least 1 rule.
// First, calculate how many rules do we need to create.
foreach(\$all_question as \$question) {
}
// Parse all rules.
\$ruleArr = array();
\$ruleArrStr = array();
\$lastQ = count(\$all_question)-1;
\$lastC = \$lastQ;
for (\$i = 0; \$i < \$rules; \$i++){
// Set the array to work with.
for (\$c = 0; \$c < count(\$all_question); \$c++){
\$ruleArr[\$i][\$c] = 1;
}
// Prep the first search string.
\$str = implode(', ', \$ruleArr[\$i]);
// Run the loops.
while(array_search(\$str, \$ruleArrStr)!==false){
\$ruleArr[\$i][\$lastC] = 1;
\$lastC-=1;
if(\$lastC<0){break 2;}
}
\$ruleArr[\$i][\$lastC] += 1;
\$lastC = \$lastQ;
// Keep the loop running if needed.
\$str = implode(', ', \$ruleArr[\$i]);
}
// Save these strings that fit.
\$ruleArrStr[\$i] = implode(', ', \$ruleArr[\$i]);

}```

I have to admit, yours does look a hell lot nicer

Probably also works faster... less searching and so on...

Maybe i'll translate it to php anyways...

Thanks man !!!
