I have been given 2 strings namely A and B and I have to find the no. of strings lying between A and B where the inbetween lying strings must be formed only from the characters of A.

Another restriction is that each letter has to be used exactly once.

For example :

A->abc

B->ddd

Ans=5

From string abc, the strings obtained are acb, bac, bca, cab, cba, all of them are larger than abc, but smaller than ddd. So the answer is 5.

Also, it may be the case that a given character in the string may repeat any number of times.ie- the below case is also included in the problem statement.

A->abacaba

B->ubuduba

Ans=64

How do I find the no. of such strings ?

I have been given an array whose elements lie between [1,70] and the size of array [1,10^5].

I have to find the total number of subsets whose all elements multiply to give a perfect square number.

Since, count of subsets can be very large, I have to give the ans mod (10^9 + 7).

How should go on to solve this problem ?

One hint given to me is to utilise the range of value that every array element hold which is [1,70] and total no. of prime numbers between these [1,70] are 19.

you are given two arrays .You have to print minimum number of swap operation to perform so that the median of two arrays are equal. if not possible then print -1.
