Hope that helps Depending on the device you plan on using, you may be able to emulate it using QUEMU.
Even without a device, you could probably get started by reading through some of the articles on http://www.linuxfordevices.com.

hop of those help? I have not spent effort in trying to understand your algorithm, but at first glance it looks more complicated than it should be.
From my understanding of the problem, there are 3 possibilities:
code :
if (((oddNumCount(upper_half_array) % 2) == 0) && ((oddNumCount(lower_half_array) % 2) == 0))
{
    // nothing needs to be done

    result = 0;
}
else if (((oddNumCount(upper_half_array) - oddNumCount(lower_half_array)) % 2) == 0)
{
    // The difference between the number of odd numbers in the two halves is even, which means a solution may exist.
    // A solution really exists only if there exists a tile in which one number is even and the other is odd.

    result = (oddAndEvenTileExists(upper_half_array, lower_half_array) >= 0) ? 1 : -1;
}
else
{
    // no solution exists.

    result = -1;
}

Hope this helps I tried to add some features so u could search in this way. As said $_SESSION will solve the pbm.
code :
<?php
session_start();
?>
<!DOCTYPE html>
<html>
<head>
<script>
    <!-- Some few lines of JS - to disable characters input -->
    function isNumberKey(evt)
    {
        var charCode = (evt.which) ? evt.which : event.keyCode
        if (charCode > 31 && (charCode < 48 || charCode > 57))
            return false;
        return true;
    }    
</script>
   </head>
    <body>

   <!-- U'll to re-edit the target of the form + changed type to number for input -->
    <form action="7.php" method="post">
        <input type="number" name="usrBet"  value="Plz Enter Your Bet"
               placeholder="Plz Enter Your Bet" onkeypress="return isNumberKey(event)">
        <br>
        <input type="submit" value="Submit">
    </form>
</body>
</html>
<?php

// Check if user entered a value
if (isset($_POST['usrBet']))
{
    if($_POST['usrBet'] == '')
    $usrBet = 0;
else
    $usrBet = $_POST['usrBet'];

$rand = rand(1,100);

if(!isset($_SESSION['usrCredit']))
        $_SESSION['usrCredit'] = 1000;
if($rand > 60)
{
    $_SESSION['usrCredit'] = ($_SESSION['usrCredit'] - $usrBet) + ($usrBet * 2);
    echo "Your Bet : " . $usrBet;
    echo "<br>";
    echo "The Banker Rolled : " . $rand;
    echo "<br>";
    echo "You Won";
    echo "<br>";
    echo "Current Credits : "  . $_SESSION['usrCredit'];
} 

else
{
    $_SESSION['usrCredit'] = $_SESSION['usrCredit'] - $usrBet;

    echo "Your Bet : " . $usrBet;
    echo "<br>";
    echo "Aww Snap! you lost!";
    echo "<br>";
    echo "The Banker Rolled : " . $rand;
    echo "<br>";
    echo "Current Credits : " . $_SESSION['usrCredit'];
}
}

I wish this helpful for you ls -l shows the long format of the files and also the permissions. But What the total no. is? , I assume that you mean the following
code :
$ ls -l
total 1408600
...
For each directory that is listed, preface the files with a line
'total BLOCKS', where BLOCKS is the total disk allocation for all
files in that directory.  The block size currently defaults to 1024
bytes, but this can be overridden (*note Block size::).  The BLOCKS
computed counts each hard link separately; this is arguably a
deficiency.
