前端起起落落落落落落落落落落落落落落落落
上回說到學習狀态，這回就來說說學習中遇到的難點哇！
難度排行：
1.輪播圖
當屬第一的莫過于輪播圖啦！在還沒學他之前，我就聽說這厮是個讓所有進階程式員掉頭發的利器，我本着明知山有虎，偏向虎山行。喝最烈的酒，日最野的狗的原則，向輪播圖發起了猛烈的進攻，不過不錯所料，我敗啦！當我就打算放棄他的時候，突然，靈感就像一道閃電，從腦海中劃過，機靈的我順手拍照，正好保留下了這一寶貴曆史時刻。一點一點的思路來了，不熟的訓示點也慢慢浮出水面。最後也勉強算是功課了這個難關吧。
難度：******。
2.幸運大輪盤抽獎
如果輪播圖是大哥的話哪幸運大輪盤就是二哥了，可以說是在老師下達了這個作業後，我就感覺毫無思路，自信心離我而去了，腦袋就想漿糊，無所适從，不知道該從哪裡入手，甚至連布局都不知道該從哪路入手。就在我迷茫之際，老師開始講思路了，他就好想漫漫黑夜中的一盞明燈
照亮了我回家的路。順手附上我的撩妹大轉盤代碼

望各位單身程式員早日脫單
現總結到這下回再說我遇到的其他大哥代碼，我還有罰抄十遍沒寫呢！
