--- title: Combinations id: 5958469238c0d8d2632f46db challengeType: 5 videoUrl: '' localeTitle: Combinações --- ## Description
Tarefa:

Dados inteiros não negativos m e n , geram todas as combinações de tamanho m dos inteiros de 0 (zero) a n-1 na ordem classificada (cada combinação é classificada e a tabela inteira é classificada).

Exemplo:

3 pente 5 é: 

 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
## Instructions
## Tests
```yml tests: - text: combinations é uma função. testString: 'assert(typeof combinations === "function", "combinations is a function.");' - text: 'combinations(3, 5) devem retornar [[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]] .' testString: 'assert.deepEqual(combinations(testInput1[0], testInput1[1]), testOutput1, "combinations(3, 5) should return [[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]].");' - text: 'combinations(4, 6) devem retornar [[0,1,2,3], [0,1,2,4], [0,1,2,5], [0,1,3,4], [0,1,3,5], [0,1,4,5], [0,2,3,4], [0,2,3,5], [0,2,4,5], [0,3,4,5], [1,2,3,4], [1,2,3,5], [1,2,4,5], [1,3,4,5], [2,3,4,5]]' testString: 'assert.deepEqual(combinations(testInput2[0], testInput2[1]), testOutput2, "combinations(4, 6) should return [[0,1,2,3], [0,1,2,4], [0,1,2,5], [0,1,3,4], [0,1,3,5], [0,1,4,5], [0,2,3,4], [0,2,3,5], [0,2,4,5], [0,3,4,5], [1,2,3,4], [1,2,3,5], [1,2,4,5], [1,3,4,5], [2,3,4,5]]");' ```
## Challenge Seed
```js function combinations (m, n) { // Good luck! return true; } ```
### After Test
```js console.info('after the test'); ```
## Solution
```js // solution required ```
