返回所有的最長回文子串 O n
用馬拉車演算法將回文半徑p i 求出來，回文字串的長度就是p i 1,起始的下標就是 i p i 2，遍歷一次p i 陣列將所有最大長度的 字串存到vector就可以了。include using namespace std string solve string s,vector v vector...
口罩外觀視覺檢測裝置 檢測市面上所有的口罩
未耒 lei 智慧型 敬上 還在用人工檢測平面口罩 kn95類口罩 kf系列口罩嗎？成本高不？檢測效果理想不？合格品的合格率達標不？檢測速度跟得上生產速度不？這些問題困擾的煩心不？300字小短文，歡迎您的閱讀，整不好咱就不煩心了呢？先說檢測類目 1 表面字元 logo，有條紋碼咱也可以檢測的 2 異...
