#x 0s, y 1s, and z 2s

Do you already have checks like "When biggest number > sum of 2 smallest numbers * 2 + 2 there is no such string"?
Pretty sure the math approach is better.
Usually in these problems there is a math trick you need to know.
The other thing you can do is make up test cases and try to find a failing test.
Try 1 2 8 maybe
Once you have a failing test you can track down what is going wrong.
for (int x = 1; x < 100; x++) {
for (int y = x; y < 100; y++) {
for (int z = y; z < 100; z++) {
const bool should_succeed = z > (x + y) * 2 + 2;
const bool actually_succeeded = makeString(x, y, z)[0] != 'N';
if (should_succeed != actually_succeeded) {
std::cout << "Failed for case " << x << ' ' << y << ' ' << z << '\n';
}
}
}
}
Maybe this helps. You can also extend it to check whether the string is valid by counting the characters and checking for tripples.
Also 0 0 0 might be worth testing.
Also check whether it's something dumb, like you returned "No such string", but "no such string" would have been correct.
Or missing whitespaces or something
