Hey

Solution:- https://www.codechef.com/viewsolution/35732806

can someone point out mistake in my code of CHMODā¦followed as per the hints aboveā¦precalculated the frequencies of each prime in dummy arrayā¦but getting WA when submitted.

here is my code

Hey @rishup_nitdgp

In kth prime problem if k==1 how can answer be number of primes in range (a,b).

e.g. INPUT : 2 5 1

then according to you answer should be 3 (as 2 3 5 are prime) but answer is 4(as 2 ,3,4,5 have only 1 prime divisor)

Can anyone explain me the āhint 2ā mentioned for problem Chef and Squares?

I understood that it would be factor of such two numbers which can be expressed as sum of two numbers X and M and other can be expressed as difference of X and Mā¦ But at this point what will be the efficient way to check if we have such the divisors which can be expressed as sum of X and M and difference of X and M?

can anyone tell why my output Is wrong ??

problem (Yet Another Problem About Sequences)

code https://www.codechef.com/viewsolution/37186669

I think it should pass partial test case.

For full test case values becomes more than 1e9.

Help would be much appreciated.

why will prefix sum in CHMOD fail ??

Iām getting WA using matrix exponentiation in sub task 2.

Here is my code

Please help

Thnx in advance
