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'];
}
}
?>

 why ls -l command in linux shows total count? What is that total about?
By : Mayco Douglas Lacerd
Date : March 29 2020, 07:55 AM
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.
