给定非负整数m和n ,以排序顺序生成从0 (零)到n-1的整数的所有大小m个 组合 (每个组合被排序并且整个表被排序)。
例:3梳子5是:
0 1 2 0 1 3 0 1 4 0 2 3 0 2 4 0 3 4 1 2 3 1 2 4 1 3 4 2 3 4
combinations
是一种功能。
testString: 'assert(typeof combinations === "function", "combinations
is a function.");'
- text: 'combinations(3, 5)
应返回[[0, 1, 2], [0, 1, 3], [0, 1, 4], [0, 2, 3], [0, 2, 4], [0, 3, 4], [1, 2, 3], [1, 2, 4], [1, 3, 4], [2, 3, 4]]
