WebApr 28, 2015 · The idea is to start from first index (index = 0) in data [], one by one fix elements at this index and recur for remaining indexes. Let the input array be {1, 2, 3, 4, 5} and r be 3. We first fix 1 at index 0 in data [], then recur for remaining indexes, then we fix 2 at index 0 and recur. Finally, we fix 3 and recur for remaining indexes. WebLinear combinations are obtained by multiplying matrices by scalars, and by adding them together.
