建议更改随机数生成方式

[JOHNYXUU]

由于您代码中的随机数生成是固定的，导致每次第一次出现的cxk图片都是固定的，非常影响观感，建议修改
随机数生成代码如下
`function rnd( seed ){
seed = ( seed * 9301 + 49297 ) % 233280; //为何使用这三个数?
return seed / ( 233280.0 );
};

function rand(number){
today = new Date();
seed = today.getTime();
return Math.ceil( rnd( seed ) * number );
};

myNum=(rand(5));`

Does your function guarantee uniform distribution? If not, we should stick to Math.random.
To introduce nondeterminism, we can discard k results from PRNG, where k depends on system time.

tbh，i get those functions from others, if u doubt the uniform distribution of function,u can go there
