How can you find the nodes with repetetive data in a linked list?





Write a prog to accept a given string in any order and flash error if any of the
character is different. For example : If abc is the input then abc, bca, cba, cab
bac are acceptable but aac or bcd are unacceptable.

abc would give you abc, acb, bac, bca, cab, cba. You can assume that all the characters
will be unique.
