    2 *
    3 * the Fibonacci Sequence are the numbers
    4 * in the folowing integer sequence.
    5 * 0 1 1 2 3 5 8 13 21 34 55 89 144 …
    6 *
    7 * starting whith 0 and 1 and each subsequent number
    8 * is the some of the previous two.
    9 *
    10 * 0 + 1 = 1 1 + 1 = 2 1 + 2 = 3 2 + 3 = 5 3 + 5 = 8 …

    In the for loop why the loop runs fibnum-2 times?
