2. Rearranging a Word
Given word, return the next alphabetically greater string in all permutations of that word. If there
is no greater permutation, return the string 'no answer'instead.
Example
word = 'baca'
The string 'baca' has the following permutations in alphabetical order: 'aabc', 'aach', 'abac', 'abca',
'acab', 'acba', 'baac', 'baca', 'bcaa', 'caab', 'caba', and 'cbaa'. The next alphabetically greater
permutation of the original string is 'bcaa'.
Function Description
Complete the function rearrangeWord in the editor.
rearrangeWord has the following parameter(s):
string word: the string to analyze
Returns
string: Return the next alphabetically greater permutation of the string. If no such string exists,
return the string 'no answer'.
Constraints
