problem(asap):

: Generate an ordered sequence of 4 unique alphabets (A-Z), where an

ordered sequence is one which is arranged in ascending alphabetic

order.

Eg. Ordered : ABCD, BCHU, KRXZ

Unordered : DCBA, BNMA

Write a function getOrderedSet() to generate sets of such 4-alphabet

sequences.

Thanks
