Program 12: Write a program that accepts a string as input from the user and checks whether the string is a palindrome
or not.
Ans. def reverseStr(str1):
'''
Objective: To reverse a string
Input Parameter: str1 - string
Return Value: reverseStr - reverse of str1
'''
reverseStr = ''
for i in range(len(str1)):
reverseStr = str1[i] + reverseStr
return reverseStr
def palindrome(string):
'''
Objective : To check whether a string is a palindrome
Input Parameter : string
Return Value : 1 if the string is palindrome, 0 otherwise
'''
reverseString = reverseStr(string)
if reverseString == string:
return 1
else:
return 0
myString = input("Enter a string: ")
result = palindrome(myString)
