Detecting cyclic pairs
Assume a std::set< std::pair >, can somebody suggest an algorithm or approach to check whether there are cyclic pairs?
e.g.
std::set< std::pair > cyclic = { {'A', 'B'}, {'B', 'C'}, {'C', 'A'} };
std::set< std::pair

Construct a circular loop in python
I want to loop a list over a cycle.
ex: I have three elements in the array L = [1,2,3]
I want to get the output as
L[0],L[1]
L[1],L[2]
L[2],L[0]
Is there a easy way get the slightly different output
L[0],L[1]
L[1],L[2]
L[0],L[2]

I have a 3d array with dimensions M x N x L, which defines the values on a cyclical volume (i.e. the M-1'th point is next to the 0th point, if we're zero indexing). If I'm given the coordinates of a point (X, Y, Z), how can I neatly find all the…

Write a function cyclical(n) that produces an n ×n pattern in which the
numbers 0 to n −1 appear in every row, but where the numbers…

Xor and Cyclic shift
Suppose we have this equation c = m ⊕ (m << 6) ⊕ (m << 10) where ⊕ stands for XOR and << for cyclic shift to the left. How can this be written as m in terms of c? What operations must be used?
I tried xoring both sides with c << 6 but didnt result…
