Question

A palindrome is a string that reads the same from the left and from the right. For example, mom and tacocat are palindromes, as are any single-character strings. Given a string, determine the number of its substrings that are palindromes. Example The string is s = 'tacocat'. Palindromic substrings are ['t', 'a', 'c', 'o', 'c', 'a', 't', 'coc', 'acoca', 'tacocat']. There are 10 palindromic substrings. Function Description Complete the countPalindromes function in the editor. countPalindromes has the following parameter: string s: the string to analyze Returns: int: an integer that represents the number of palindromic substrings in the given string Constraints • 1 ? |s| ? 5 ! 103 • each character of s, s[i] ? {'a'-'z'}.

          A palindrome is a string that reads the
same from the left and from the right. For
example, mom and tacocat are
palindromes, as are any single-character
strings. Given a string, determine the
number of its substrings that are
palindromes.

Example
The string is s = 'tacocat'. Palindromic
substrings are ['t', 'a', 'c', 'o', 'c', 'a', 't',
'coc', 'acoca', 'tacocat']. There
are 10 palindromic substrings.

Function Description
Complete the countPalindromes function
in the editor.

countPalindromes has the following
parameter:
string s: the string to analyze

Returns:
int: an integer that represents the
number of palindromic substrings in the
given string

Constraints

• 1 ? |s| ? 5 ! 103
• each character of s, s[i] ? {'a'-'z'}.
