Palindrome CountWrite a python program to count the number of palindrome strings that occurred in the given string. Input:The input consists of a string.Output:count number of palindrome stringsConstraints:1 < str < 10000Example:Input:madamOutput:2Explanation:NAPublic Test Cases:# INPUT EXPECTED OUTPUT1 madam2
Solution
Here is a step-by-step solution to the problem:
- First, we need to define a function to check if a string is a palindrome. A string is a palindrome if it reads the same backward as forward. We can achieve this by comparing the string with its reverse. If they are the same, then the string is a palindrome.
def is_palindrome(s):
return s == s[::-1]
- Next, we need to count the number of palindrome substrings in a given string. We can do this by iterating over all substrings of the string and checking if they are palindromes.
def count_palindromes(s):
count = 0
for i in range(len(s)):
for j in range(i + 1, len(s) + 1):
if is_palindrome(s[i:j]):
count += 1
return count
- Finally, we can use the
count_palindromesfunction to count the number of palindrome substrings in the input string.
print(count_palindromes('madam')) # Output: 2
This program works by generating all possible substrings of the input string and checking each one to see if it is a palindrome. If it is, it increments a counter. The final count is the number of palindrome substrings in the input string.
