第七屆福建省賽重現賽D題,概率計算不過挺有技巧的,問了acdart兄才恍然大悟(分 題意 clas tag ble cpp rand ring ++i break 題意:有n個土豆,每個有體積V(i),你可以將每個土豆等分為不超過K份,問你最大塊和最小塊比值最小為多少。
直接枚舉切法,只有n*K種,然後保證其為最大塊,去算其他塊的切法,即讓其他塊切得盡可 sin pat clas cst 發現 can -- cnblogs ret 題意:給你一張簡單無向圖(但可能不連通),再給你一個K,讓你求解任意一個問題:K染色或者輸出一條K長路徑。
直接貪心染色,對一個點染上其相鄰的點的顏色集合之中,未出現過的最小的顏色。

題意:給一個n行m列的矩陣,原矩陣按數字順序從第一行開始向後填充,尋找一種方案使得原矩陣中相鄰的數字在新矩陣中都不相鄰。
分析:沒有什麽技術含量的一道構造題,試試就可以發現方案,很多人是用隨機化過的 .com input exc 實用 ive 就是 bubuko 前言 最大 Programming in Python3 (Second Edition)實例
