p.s. why time limitation is 2sec? it can be solved very fast using Lucas theorem.

why I get crash(access violation) at test 6?
who have the test?
S.O.S!!

For example :
N = 7 and M = 3
you see : 7!/(3!*4!) = (2*3*4*5*6*7)/(2*3*2*3*4) = (5*6*7)/(2*3) = 35
=> you need not to calculate the multiple but divide all numbers into prime
I assign : the left = (5*6*7), the right = (2*3)
after division the left :
5 = 5
6 = 2*3
7 = 7
you will count all prime, the result is following :
there are 1 primes with value of 2
there are 1 primes with value of 3
there are 1 primes with value of 5
there are 1 primes with value of 7
I put into the bracket (1,1,1,1)
after divison the right :
2 = 2
3 = 3
there are 1 primes with value of 2
there are 1 primes with value of 3
there are 0 primes with value of 5
there are 0 primes with value of 7
I put into the bracket (1,1,0,0)
the left - the right = (1,1,1,1) - (1,1,0,0) = (0,0,1,1)
and the result 0+0+1+1 = 2
2 is the result
GOOD LUCK !

who have AC - please give tests.

This is my sourse and it works for some of the tests, but not for the all! So i have a problem on test 2. Can you tell me what to edit? 10x

Can someone help me? With this source it is working for 2.031. How can I improve it?

My program run in 0.741 seconds and i saw most people only needed
0.09s. How can i solve this any faster?

usually I write the program mixed with c and c++
and submit as a c++ program
and no problem occurs on every site until today's
"complilation error" on this site.

My solution works 0.02 sec :)
It needs only to find all primes from 2 to N and
in addition - O(N) time

There is a trick in finding divsors.
For example,the number of k divisor from 1~N is
F(N)=N div k+N div (k*k)+N div (k*k*k)......

So we can just calc F(N)-F(M)-F(N-M) for every divisor that is between 1 and N.
