Given the strings s 1 and s 2 that are of the same length, create a new string consisting of the last character of s followed by the last character of s2, fol lowed by the second to last character of s1, followed by the second to last character of s2, and so on (in other words the new string should consist of alte mating characters of the reverse of s1 and s2 ). For example. if s1 contained "hello" and s2 contained "world", then the new string should contain "odil Ireohw*. Assign the new string to the variable s3. Additional Notes: s1 and s2 should not be modified
