Construct a Pseudocode to determine a factorial of a number. Your algorithm must:

• Include an appropriate title.
• Ask the end-user for the number they want to find the factorial for, work out and display the factorial.
  • If the end-user chooses zero then the output should be one.
  • If the end-user chooses one then the output should be one.
• Introduce a loop, allowing the end-user the choice to find the factorial for multiple numbers.
• Clearly show all the inputs/outputs.
