You have to find a permutation of the string where no letter is followed by another letter and no digit is followed by another digit. To generate all the permutations of an array from index l to r, fix an element at index l and recur for the index l+1 to r. Backtrack and fix another element at index l and recur for index l+1 to r. Repeat the above steps to generate all the permutations. Without a Kleene star, our solution would look like this: If a star is present in the pattern, it will be in the second position e x t p a t t e r n [ 1 ] ext{pattern[1]} e x t p a t t e r n [ 1 ] . Note that there are n! ABCD, we want the 3rd subtree root node in 2nd level, just put C in the 1st place, which is CABD; For ABCDE, we want the 3rd subtree root node in the 3rd level, it is ADBCE.
