In C++, the % symbol only returns the remainder. Check the example below. #include <iostream> using namespace std; int main() { cout << -7 % 3 << endl; cout << 7 % -3 << endl; } Output: -1 1 As the output suggests, the % operator doesn’t give us modulus. It is ...
whose string label is the same as the label of the corresponding ``Symbol`` object. For example, the input ``Key("x")`` on line 29 refers to the ``Symbol("x")`` later in the file, on line 39. A ``Key`` class is used for describing inputs and outputs used for graph unroll...
