e 3 120 points] A palindrome is a sequence of characters which reads the xamples: "rotor", "Rotor" (with capital R). "step on no pets", etc. xercis same back or forward. ward Write the code for the following functions: // returns true if s is a palindrome and false otherwise bool is_ palidrome(string s); // returns the number of palindromes in vector v of strings int countPalindromes(const vector& v) Exercise 4120 points Write the implementation of the following function: // the function returns the equivalent time in seconds of // h hours, m minutes, and s seconds int toSeconds(int h, int m, int s); .Write the implementation of the following function: the function takes input parameter t which represents time in seconds //and returns the equivalent time in hours, minutes, and seconds as out // parameters void toHoursMinutesSeconds(int t, int&h, int&m, int& s); . Wirite a declaration for a structure named time_type that holds the following dat regarding a time duration expressed in: hours, minutes, and seconds Rewrite the above functions using time_type. Make sure you propose a function prototype and its implementation for each
