Program Plan Intro

Computing efficiency

Program plan:

• Import required files.
• Call the function “setrecursionlimit()” to set limit.
• Define a function “factorial()”.
  • Set the value of “fact” equal to 1
  • Iterate a for loop.
    • Set the value of “fact”.
  • Return the value of “fact”.
• Define a function “iterative_options()”.
  • Declare a variable “x” and set with value of “factorial(n)”.
  • Declare a variable “x” and set the value.
  • Return the value “x/y”.
• Define a function “recursive_options()”.
  • If the condition “k == 1”is true.
    • set the value of “options” as n.
  • Checking another condition “n < k”.
    • set the value of “options” as 0.
  • If the conditions failed.
    • Set the value of options using function “recursive_options()”.
    • Return the value of “options”.
• Define the “main()” function.
  • Print the value using “iterative_options()”.
  • Print the value using “recursive_options()”.
• Call the “main()” function.
