3. a1 − b1 ≡ a2 − b2 (mod n). Ok, this is pretty great, but it’s missing one operation! How do we performdivisionmodulo n? Or even, can we? As a reminder of how wedefined divisionway back when, we had the following definition for the number 1/n : Definition 8 Let n...
I have seen some similar functions in problems where numbers are large and we need to mod a number like 998244353 or 1000000007 (I also noticed they are all prime). I think this function might be modular inverse??? But I don't know why any of this works and how do I use it. I d...
I am unable to understand the proof of the algorithm. It would be very helpful if anyone explains the same in a simple way. m mod i = — m/i*i (mod m) , fak[0]=1fork=1...N:fak[k]=fak[k-1]*k%P . This is a result of Fermat Little Theorem and it can be computed inOl...

A naive method consists of trying all numbers from the set {0, ..., m - 1}. For every number x from this set, calculate a× x mod m, i.e., the remainder from the division of a× x by m. The modular multiplicative inverse of a modulo m is the value of x for which this ...
n. A form of integer arithmetic in which all integers having the same remainder when divided by a given natural number (called the modulus) are considered equivalent:Clocks use modular arithmetic with modulus 12, so 4 hours after 9 o'clock is 1 o'clock. ...

I have a 7x7-matrix (A) with large numbers. I used the MINVERT(matrix) formula to find A:s inverse A^(-1). The problem I got is that the inverse is wrong. When using MMULT(matrix1; matrix2) I'm not getting the unit-matrix, unfortunately. ...
There are multiple test cases. The first line of input is an integerT≈ 2000 indicating the number of test cases. Each test case contains two integers 0 <a≤ 1000 and 0 <m≤ 1000. Output For each test case, output the smallest positivex. If suchxdoesn't exist, output "Not Exist"....
