Execution is counted, but the test gives a message.

// BEGIN (write your solution here)

int main(void) {
    int lower, upper, step, celsium, kelvin;
    lower = 0;
    upper = 300;
    step = 20;

    celsium = lower;

    while(celsium <= upper) {
        kelvin = celsium + 273;
        printf("%d : %d\n", celsium, kelvin);

        celsium = celsium + step;
return 0;

There is russian sentence in "the problem" section. In all english courses in modals that appear after accomplishing the quizzes title is "Title" and text in body is "Body".
