The bubble sort algorithm sorts an array by placing the largest element in its place at each iteration. By stopping the algorithm as soon as the array is sorted, in how many iterations is the array int T[6] = {-1, 3, 42, 21, 11, 13} sorted?

After executing the following program, how many times is the string "hello" displayed?

    int cpt = 0;
    while (l <= r) {
        cpt++;
        int m = l + (r - l) / 2;
        if (t[m] == 1) {
            l = m + 1;
        } else {
            r = m - 1;
        }
    }
    printf("%d %d\n", l, cpt);
    return 0;
}

        printf("a is less than 10\n");
        printf("a is greater than 10\n");
    return 0;
}
