Program Plan Intro

Palindrome

Program plan:

• Define a function “palindrome()”.
  • If the condition “firstRun == True”is true.
  • Iterate a for loop.
    • Call a function “replace()”.
  • Call the function “lower()”.
  • If the condition “len(xStr) < 2”is true.
    • Return true
  • Check another condition “xStr[0] == xStr[-1]”.
    • Set the value of “xStr”.
    • Call the function “palindrome()”.
    • Return true.
  • If the conditions do not satisfy
    • Return false
• Define “main()” function.
  • Scan for the input values.
  • If the condition is true
    • Print the statement.
  • If the condition is not true.
    • Print the statement.
• Calling the main function
