Answer:
Explanation:
learn by picking up courses and books
but if you don't have any prior programming experience, i recommend you DON'T do c++ first, but instead use an easier language to get the hang of it, like Python.
 
        
             
        
        
        
Answer: Use a heuristic-based algorithm that suggests good locations for the scooters.
Explanation:
The best way to improve the run time of the algorithm is to use a heuristic-based algorithm as this will help in suggesting good locations for the scooters.
By using the heuristic based approach, there'll be a ranking based on available information which will then be used to suggest the locations that are good for the scooters. Its main objective is to give a solution which is vital in solving a particular problem based on the timeframe.
 
        
             
        
        
        
<u>Answer:</u>
Using transistors instead of vacuum tubes in the second-generation computers drastically reduced  the size  of the computer size.
<u>Explanation:</u>
- Transistors were smaller when compared to vacuum tubes so computers with vacuum tubes were small in size
. 
- They were also faster in speed, and cheaper to build.
- These computers also operates at lower temperature and produces less heat.
- 
In 1956, TX-0 was the first computer to build with transistors.
- Varieties of transistors under a single unit called Integrated Circuit Chip or ICs.  
- Increase in Memory size, increasing processing speed are the major achievements of ICs.
