terminate called after throwing an instance of 'std::invalid_argument' what(): stoiclass Solution { public: string complexNumberMultiply(string a, string b) { int aplus = a. find('+'); int bplus = b. find('+'); int ai = a. find('i'); int bi = b. find('i'); int a1 = stoi(a. substr(0, aplus)); int b1 = stoi(a. substr(aplus + 1, ai), nullptr); int a2 = stoi(a. substr(0, bplus), nullptr); int b2 = stoi(a. substr(bplus + 1, bi), nullptr); int aa = a1 * a2 - (b1 * b2); int ab = a1 * b2 + a2 * b1; string res = to_string(aa) + "+" + to_string(ab) + "i"; return res; }};

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
