We define the Liouville function λ(n) by setting λ(1)=1. If n>1, we consider the prime power factorization n=p_1^(a_1 ) p_2^(a_2 )…p_m^(a_m ) and define λ(n)=(-1)^(a_1+a_2+⋯+a_m ) Prove that the summatory function of λ,Λ(n)=∑_d|n┤▒〖λ(d)〗 is multiplicative.

Consider the statement, “For all natural numbers n,n, if nn is
prime, then nn is solitary.” You do not need to know what
solitary means for this problem, just that it is a
property that some numbers have and others do not.
Write the converse and the contrapositive of the statement,
saying which is which. Note: the original statement claims that an
implication is true for all n,n, and it is that implication that we
are taking the converse and...

Write a function matrix power(A, n) that computes the power
An using Boolean arithmetic and returns the result. You
may assume that A is a 2D list containing only 0s and 1s, A is
square (same number of rows and columns), and n is an integer ≥ 1.
You should call your previously written matrix multiply boolean
function.
Example: Let R = [ [0, 0, 0, 1], [0, 1, 1, 0], [0, 0, 0, 1], [0,

Consider this prime sieve in which an array of numbers of size N
is created (i.e. int nums[10] = {2,3,4,5,6,7,8,9,10,11};) and
initialized to contain counting numbers starting with 2. The sieve
works by taking each number in the array, and “crossing out”
(perhaps via a similar array of Booleans) multiples of that number.
So beginning with 2, we would “cross out” 4, 6, 8, 10. Then repeat
the process for 3, and so on. Numbers that are already “crossed
out”...
