基礎練習 組合數

題目來自 codevs 1631 洛谷 1173 很簡單的遞推題目 由劉汝佳紫皮 今後簡稱 ruka 衍伸想要做的這道題目 稍後我將ruka版 發上來 本題 如下 include include define num 100003 using namespace std long long a 10...

演算法練習 排列組合之組合和

給出一組不同的正整數序列和乙個目標值，求出全部可能的組合，使得組合裡全部元素和為目標值。要求 1 每乙個組合裡的元素依照公升序排列。2 輸出組合裡不含有反覆的組合。3 輸入序列中的整數能夠多次使用。舉例 輸入 目標值為7 輸出。為了讓輸出元素按公升序排列，可對輸入序列進行排序。同這裡我們使用遞迴的方...

練習，求組合公式值

求組合數公式為 編一程式，輸入m和n 的值，求組合數。要求分別定義求階乘和求組合的函式，求組合數的函式呼叫求階乘的函式來實現求解，在 main 函式中，負責輸入輸出及呼叫求組合數的函式。include using namespace std int fac int int main int m,n ...
