Why is it difficult to store linked list in an array?
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.
Write out a function that prints out all the permutations of a string. For example,
abc would give you abc, acb, bac, bca, cab, cba. You can assume that all the characters
will be unique.
