C(n,m) ---n是下标 , m是上标 (C上面m，下面n)，C(n,m) 表示 n选m的组合数，等于从n开始连续递减的m个自然数的积除以从1开始连续递增的m个自然数的积。例子:C(8,3)=8*7*6/(1*2*3) =56 分子是从8开始连续递减的3个自然数的积 分母是从1开始连续递增的3个自然数的积 ...
Given two integersnandk, return all possible combinations ofknumbers out of 1 ...n. 解析:同求全部组合的过程一样,只是这里限制每个组合中元素的个数为k,求所有组合时并不限制元素个数。 若要排除重复的元素,则首先对所有元素进行排序。 代码: publicstaticList<List<Integer>> getAllCombinations(int[] a...
