Question

Write a complete method including header that takes two Strings as arguments and returns true if the second string is the same as the first string but in reverse! OR Option 2 (minus 1.5 marks for this option): do the same task but return true if the two strings have exactly the same characters. For either option, your solution must use loops to do the work, your method must be reasonably efficient by ending as early as possible and charAt (i) might be helpful. Complete only one option. Do not do both options.
