A word is a palindrome if it reads the same backward as it does forward (ex. racecar, rotator, abccba). Write a program to determine whether or not the characters in a given string can be rearranged into a palindrome. For example, the letters in 'cabcba' can be rearranged into 'abccba', which is a palindrome. The user will always input letters in lowercase, with no spaces or punctuation. Display 'Yes!' if the letters of a given string can be arranged into a palindrome; otherwise display 'No!!. Note: You do not have to rearrange the letters, simply determine whether or not it is possible to create a palindrome out of the given string. Test Case 1: Enter a string of characters: raacrec Yes! Test Case 2: Enter a string of characters: abc No! Test Case 3: Enter a string of characters: ycycych No! Test Case 4:
