Write a function xmult() that takes two lists of integers as input and returns a list contain- ing all products of integers from the first list with the integers from the second list. >>> xmult([2], [1, 5]) [2, 10] >>> xmult([2, 3], [1, 5]) [2, 10, 3, 15] >>> xmult([3, 4, 1], [2, 0]) [6, 0, 8, 0, 2, 0]

3. consider the following class definitions: class smart class supersmart: public smart { { public: public: void print() const; void print() const; void set(int, int); void set(int, int, int); int sum(); int manipulate(); smart(); supersmart(); smart(int, int); supersmart(int, int, int); private: private: int x; int z; int y; int secret(); }; }; . which private members, if any, of smart are public members of supersmart? a. which members, functions, and/or data of the class smart are directly accessible in class supersmart?

Our primary purpouse as electricians is to do wich of the following core concepts? a: install electrical components in a way they can be upgraded b: install electrical equiptment in a way that reduces heat c: install electrical systems in a safe manner d: only b and c

The following function returns a string of length n whose characters are all 'x'. give the order of growth (as a function of n) of the running time. recall that concatenating two strings in java takes time proportional to the sum of their lengths. public static string f(int n) { if (n == 0) return ""; if (n == 1) return "x"; return f(n/2) + f(n - n/2); } options: a) constant b) logarithmic c) linear d) linearithmic e)quadratic f)cubic g) exponential
