How do you count the number of palindromes in a string?
countPalin() function counts the number of palindrome words by extracting every word of the string and passing it to checkPalin() function. An extra space is added in the original string to extract last word. checkPalin() function check the word palindrome. It returns 1 if word is palindrome else returns 0.
How do you count the number of palindromes in a string in python?
Palindromic Substrings in Python
- count := 0.
- for i in range 0 to length if string. for j in range i + 1 to length of string + 1. temp := substring from index i to j. if temp is palindrome, then increase count by 1.
- return counter.

There may be more than one solution, but any will do. If the word is already a palindrome or there is no solution, return -1. Otherwise, return the index of a character to remove. Either remove ‘b’ at index or ‘c’ at index .
