I have to calculateA^bwhere A^b can be a huge number then find The SOD(Sum of divisors) of that number. So, If I calculateSOD(bigmod(A,b,mod))will this return the same value asSOD(A^b) % mod Asking for this As I am getting WA and could not get where I mistaken... Link ...
(*number of flags*, *number of barbs*, *half_flag*, *empty_flag*) *half_flag* is a boolean whether half of a barb is needed, since there should only ever be one half on a given barb. *empty_flag* flag is an array of flags to easily tell if a barb is empty (too low to p...
We study a class of problems called Modular Inverse Hidden Number Problems (MIHNPs). The basic problem in this class is the following: Given many pairs xi, msbk (α + xi)-1 mod p for random xi ∈ Zp the problem is to find α∈ Zp (here msbk(x) refers to the k most ...

As a reminder of how wedefined divisionway back when, we had the following definition for the number 1/n : Definition 8 Let n ∈ N and let a ∈ Z. We say that u is if au ≡ 1 (mod n). So, in Example 8, we showed that5 is a multiplicative inverse for 3 modulo 7. ...

I was practicing DP through CSES when I got to theTwo Sets IIproblem, wherein I got the confusion on the usage of mod to get the correct answer. I had read earlier that if we wish to take mod of a summation, we have to take mod of individual elements of the series and then take...
If you are seeing a large number of these warnings for a mod that you have used extensively already, and know that it doesn't have problems, then you can add a mod-level rule to ignore the warnings:On the other hand, you shouldn't ignore every warning, because some of them are real...
