Assume p(x)=x10−x5+1p(x) = x^{10} - x^5 + 1p(x)=x10−x5+1 and A=[−2−613]A = \begin{bmatrix} -2 & -6 \\ 1 & 3 \end{bmatrix}A=[−21−63]. Let p(A)=[abcd]p(A) = \begin{bmatrix} a & b \\ c & d \end{bmatrix}p(A)=[acbd]. What is ⌊∣a+b+c+d∣⌋%5\lfloor |a+b+c+d| \rfloor \% 5⌊∣a+b+c+d∣⌋%5? (% is the modulo operation. ⌊z⌋\lfloor z \rfloor⌊z⌋ rounds zzz to the smaller nearest integer.)
