Question: Given matrix; Evaluate A ^ 1 + A ^ 2 + A ^ 3 +... A ^ K Using quick power Sum (6) = A ^ 1 + A ^ 2 + A ^ 3 + A ^ 3 * (A ^ 1 + A ^ 2 + A ^ 3 )... So you can get a general item. Sum (n) If (n 1) { Sum (n) = sum (n-1) * A ^ n; } Else sum (n) = sum (n/2) + A (n/2) * sum (n/2 ); #include #include #include #include #include #define N 30typedef long long LL;using namespace std;int n,mod;struct

The number of times the given matrix chain multiplication expression needs to be calculated. The number of columns in the current matrix is equal to the number of rows in the next matrix. The result is an invalid error. The input is strictly legal. Even if only two characters are multiplied, the input is enclosed in parentheses. If there are at most two character

When the plane is set to (NX,NY,NZ,D), the column main sequence reflection matrix with this planar mirror is as follows:The derivation is as follows:One, the expression of the platform:, over point P, the plane of the normal vector n, can be expressed as:Np+d=0where D is the forward distance from the plane to the origin point. If the plane faces the origin, D is positive and D is negative if the plane is back to the origin point.So the plane can be re

Problem DescriptionOne day, Alice and Bob felt bored again, Bob knows Alice was a girl who loves math and are just learning something about mat Rix, so he decided-make a crazy problem for her.Bob has a six-faced dice which have numbers 0, 1, 2, 3, 4 and 5 on each face. At first, he'll choose a number N (4 Step 1:calculate a new n*n matrix C = a*b.Step 2:calculate M = c^ (n*n).Step 3:for each element x in M, calculate x% 6. All the remainders form a ne
