Question

I got this line of code that pops a int of the array saves it to int element then removes it from array. then in the return statement return CountCriticalVotes(rest, blockIndex + element); it ads it to the blockIndex variable and if it reaches 10 before the array is empty it returns 1. But my problem is this, I do not want it to add up all the values in the array in the parameter, but only add one then revert the parameter value back to it´s original state, then add a new, revert etc… How would i do this?

int NumCriticalVotes :: CountCriticalVotes(Vector<int> & blocks, int blockIndex)
{
    if (blockIndex >= 10)
    {
        return 1;
    }
    if (blocks.isEmpty())
    {
        return 0;


    } else {

        int element = blocks.get(0);
        Vector<int> rest = blocks;
        rest.remove(0);
        return  CountCriticalVotes(rest, blockIndex + element);

Doing it recursively (very inefficient by the way. no reason to do this):

bool NumCriticalVotes :: CountCriticalVotes(Vector<int> const& blocks,
                                            int blockIndex,
                                            size_t current = 0)
{
    // check if we reach the end of the vector
    if (current == block.size())
    {
        return true;
    }

    int sum = blockIndex+block.get(current);

    if (sum >= 10)
    {
        return true;
    }

    return  CountCriticalVotes(blocks, blockIndex, current+1);
}
