/**
 * @file ft_strrchr.c
 * @brief The ft_strrchr() function locates the last occurrence of c (converted 
 * to a char) in the string pointed to by s. The terminating null character is 
 * considered to be part of the string; therefore if c is `\0', the functions 
 * locate the terminating `\0'.
 *
 * @param str The string to be searched.
 * @param c The character to be located.
 * @return A pointer to the located character, or NULL if the character does 
 * not appear in the string.
