            # linear walk updating the number of remaining steps.
            
            steps = 1
            for v in nums[:-1]:
                steps -= 1
                if v == 0 and steps == 0:
                    return False
                else:
                    steps = max(steps, v)
            
            return True
    

    This seems easier to read and understand than the editorial solution. Since you are given the opportunity to move up to x steps at each given index, you can just keep a running total of the total number of steps you have remaining, and update them while parsing each element in the list. That means subtracting 1 for each step, then either continuing with the steps you have, or instead using the steps given at that index.
