Convierta la string en una string de palíndromo cambiando solo un carácter

Dada una string str. Compruebe si es posible convertir la string en una string de palíndromo cambiando solo un carácter.
Ejemplos: 
 

Input : str = "abccaa"
Output : Yes
We can change the second last character
i.e. 'a' to 'b' to make it palindrome string

Input : str = "abbcca"
Output : No
We can not convert the string into palindrome
string by changing only one character.
