PROGRAMMING:The first t combination results
Combination results
Find out any combination of R (0 < R < = n) numbers from natural numbers 1, 2,..., n (0 < n < = 30), and output the first t combination results.
###Input format:
Enter n, R, t (1 < = T < = C (n, R)) on one line.
###Output format:
Output the first t combination results in a specific order, each combination result takes up one line, each integer including the first integer is preceded by a space, and there is no space after the last integer.
Specific order: the values in each combination result are arranged from large to small, and the combinations are arranged in reverse dictionary order.
###Input example:
Here is a set of inputs. For example:
```in
5 3 10
```
```in
6 4 8
```
###Output example:
The corresponding output is given here. For example:
```out
5 4 3
5 4 2
5 4 1
5 3 2
5 3 1
5 2 1
4 3 2
4 3 1
4 2 1
3 2 1
```
```out
6 5 4 3
6 5 4 2
6 5 4 1
6 5 3 2
6 5 3 1
6 5 2 1
6 4 3 2
6 4 3 1
