//使用for循环, 通过arraysSimilar函数验证以上数据是否相似，如相似显示“通过”,否则"不通过",所以大家要完成arraysSimilar函数,具体要求，详见任务要求。
for(var i=0;i<cases.length;i++){
if(arraysSimilar(cases[i].arr1,cases[i].arr2)!==cases[i].expect) {
document.write("不通过！case"+(i+1)+"不正确！arr1="+JSON.stringify(cases[i].arr1)+", arr2="+JSON.stringify(cases[i].arr2)+" 的判断结果不是"+cases[i].expect);
return false;
}
}
return true;
}();
document.write("判定结果:"+(result?"通过":"不通过"));index.html是我的提交，请大家帮忙看看
