哪位帮个忙看看

[苦逼热狗]

我有个问题，嘿嘿，就是这个

Step 1: Generate a file of 10,000 fibonacci numbers, each number on a line
The start should look like:
0
1
1
2
3
5
8
13
21
etc

Step 2: You need to calculate the signed int crc32 values of each line.
The start should look like:
-186917087
-2082672713
-2082672713
450215437
1842515611
etc

Step 3: Then multiply any negative line by -1.
Step 4: Find the largest value and remember it
Step 5: Then add all the resulting values (including the largest one), e.g. result 1 + result 2 + etc...
Step 6: Then multiply that with the largest value from step 4
我写的code得到的结果居然不是正确的
不知道逻辑那里出错误了
哪位有空帮忙看看，多谢了

<?
$vala = 0; //第一个fibonacci numbers
$valb = 1; //第二个fibonacci numbers

$max = 0; //最大值
$total = 0;//$vala + $valb; //sum of all

$val = array();  //保存所有fibonacci numbers
$crc = array(); //保存所有crc32 values 


array_push($val, $vala); //push 0 into array
array_push($val, $valb); //push 1 into array

//Step 1 : fibonacci numbers
for ($i = 0; $i<5000;$i++){

	$vala = $vala + $valb; //calculate fibonacci numbers
	$valb = $vala + $valb; //calculate fibonacci numbers

        array_push($val, $vala); //push $vala into array
        array_push($val, $valb); //push $valb into array

	$total = $vala + $valb + $total; //calculate total
}

//Step 2 : CRC Value
foreach ($val as $rawline) {

    $CRC_Val = crc32($rawline); //calculate CRC32 Value
    array_push($crc, $CRC_Val); //push $CRC_Val into array

    $total = $CRC_Val + $total; //calculate total
}
foreach ($crc as $rawline) {

    //Step 3: Then multiply any negative line by -1.
    if ( $rawline < 0 ){  //如果小于0
	$rawline = $rawline * -1; //multiply by -1
    }

    //Step 4: Find the largest value and remember it
    if ( $rawline > $max ){ //如果大于最大值
	$max = $rawline;  //reintialize it to rawline
     }

    $total = $rawline + $total; //calculate total
}

    //Step 5: Then add all the resulting values (including the largest one)
    $total = $total + $max;

    //Step 6: Then multiply that with the largest value from step 4
    $total = $total * $max;

    print $total;
?>

我知道这个total应该是错误的，就是不知道他到底题目是什么鸟意思
Then add all the resulting values (including the largest one)
是要我
从step1就开始加起呢
还是从step3加起然后再加上largest
或者2......

我的答案还是和原来说的一样~

- -
不过你也知道test时候
它老说说wrong answer

 

[苦逼热狗]

有人提议
删除 $total = $total + $max;

$total = $vala + $valb + $total; //calculate total
$total = $CRC_Val + $total; //calculate total
不过结果还是错误.sign

。。。。。。。。。。。。。

我帮你问问别人好了~

如果那个人有起床的话~
