我没有随机数据的一部分。我不需要我必须付费才能获取数据的帐户吗？
很天真。这是为“ 1Aa”（49、65、97）生成的代码，并带有一些文档：
// field 0 and 1 are loop counters.
// The fields 2, 3 and 4 are for "1", "A" and "a"
++++++++++[ // do 10 times
>
++++++++++[ // do 10 times
> // "1" (49) is below 50 so we don't need to do anything here
>+ // When the loops are done, this part will have increased the value of field 3 by 100 (10 * 10 * 1)
>+ // same as above
<<<- // decrease inner loop counter
]
>+++++ // this will add 50 (10 * 5) to field 2, for a total of 50
>---- // subtract 40 from field 3, total of 60
> // Nothing done, value stays at 100
<<<<- // decrease outer loop counter
]
>>-. // subtract 1 from field 2, total now: 49, the value for "1"
>+++++. // add 5 to field 3, makes a total of 65, the value for "A"
>---. // subtract 3 from field 4, total of 97, the value for "a"
Java代码有点丑陋，但是可以工作。平均字节值越高，每个输入字节比率生成的指令越好。
如果要运行它，则必须将Lenna.png与.class文件放在同一目录中。它将分数打印到控制台，并将生成的BF代码写入名为“ output.txt”的文件中。

我将进行一些小的改进，但可能不会做很多改进。 做完了
