如何在一排中找到匹配的硬幣？

Question

我想在一排中找到匹配的硬幣面。我設法讓一行中的3個匹配的尾巴結束循環。

但我怎麼能包括頭（它似乎忽略頭）？

例如：

0 is heads 
reset 
0 is heads 
reset 
1 is tails 
1 is tails 
1 is tails 
total flips took is: 5 

PHP：

$flipCounts = 0; 
$matchingFaceTypes = 0; 

$targetReached = false; 
while ($matchingFaceTypes < 3) { 
    $faceType = rand(0, 1); 
    $flipCounts++; 
    if($faceType == 0) { 
     $matchingFaceTypes++; 
     echo $faceType . " is heads ". "\n"; 
     } 
    if($faceType == 1) { 

     $matchingFaceTypes++; 
     echo $faceType." is tails ". "\n"; 

    } else { 
      $matchingFaceTypes =0; 
      echo " reset ". "\n"; 
     } 
    } echo "total flips took is: " . $flipCounts;

$maxMatches = 3; 
$matches = array('tails' => 0, 'heads' => 0, 'total' => 0); 

while(max($matches['tails'], $matches['heads']) < $maxMatches) { 
    $faceType = rand(0, 1); 
    if ($faceType) { 
     $matches['heads']++; 
     $matches['tails'] = 0; 
     echo $faceType . " is heads\n"; 
    } 
    else { 
     $matches['tails']++; 
     $matches['heads'] = 0; 
     echo $faceType . " is tails\n"; 
    } 
    $matches['total']++; 
} 

echo "total flips took is: " . $matches['total']; 

說到最大的（

$maxMatches = 3; 
$total = 0; 
$matches = array('tails' => 0, 'heads' => 0); 

while(max($matches) < $maxMatches) { 
    $faceType = rand(0, 1); 
    if ($faceType) { 
     $matches['heads']++; 
     $matches['tails'] = 0; 
     echo $faceType . " is heads\n"; 
    } 
    else { 
     $matches['tails']++; 
     $matches['heads'] = 0; 
     echo $faceType . " is tails\n"; 
    } 
    $total++; 
} 

echo "total flips took is: " . $total;

的其他物質是指第二個如果，這樣的人會採取，如果$ facetype == 0

下一個問題是：你不檢查是否最後一個類型是之前的類型

我建議一個變量叫做$lasttype，並檢查是否$faceType等於說，如果沒有重置計數器，之後做輸出）

$flipCounts = 0; 
$matchingFaceTypes = 0; 
$ctype=0; 
$targetReached = false; 
$lasttype=-1; 

while ($matchingFaceTypes < 3) { 
    $faceType = rand(0, 1); 
    $flipCounts++; 
    if($faceType != $lasttype) { 
     if($lasttype!=-1) 
      echo " reset ". "\n<br/>"; 
     $lasttype=$faceType; 
     $matchingFaceTypes =0; 
    } 

    if($faceType == 0) { 
     $matchingFaceTypes++; 
     echo $faceType . " is heads ". "\n<br/>"; 
    }else{ 
     $matchingFaceTypes++; 
     echo $faceType." is tails ". "\n<br/>"; 
    }  
} 
echo "total flips took is: " . $flipCounts;
