Develop an algorithm, using either pseudo-code or a flowchart, that helps a rooftop solar cooperative estimate the daily energy generation (in kWh) of a solar panel installation based on forecast conditions.

Your algorithm should:

• get the user to enter whether the season is "summer" or "winter"
• get the user to enter the forecast cloud cover percentage (they should enter an integer between 0 and 100 inclusive; if the number falls outside of this range then they should be made to re-enter another number until they enter a valid cloud cover)
• calculate the base solar energy generation (in kWh) using the following rules:
  • 24 kWh is generated if the cloud cover is between 0% and 20% inclusive,
  • 15 kWh is generated if the cloud cover is between 21% and 60% inclusive,
  • and 6 kWh is generated if the cloud cover is higher than 60%
• decrease the estimated generation by 60% (multiply by 0.4) if the season is "winter"
• output the final estimated daily energy generation.
