    1st bit --> 2^0 = 1 (Any positive integer raised to the 0th power = 1.)

    2nd bit --> 2^1 = 2 (2 = 2)

    3rd bit --> 2^2 = 4 (2 X 2 = 4)

    4th bit --> 2^3 = 8 (2 X 2 X 2 = 8)

    5th bit --> 2^4 =16 (2 X 2 X 2 X 2 =16)

    6th bit --> 2^5 = 32 (2 X 2 X 2 X 2 X 2 = 32)

    7th bit --> 2^6 = 64 (2 X 2 X 2 X 2 X 2 X 2 = 64)

    8th bit --> 2^7 = 128 (2 X 2 X 2 X 2 X 2 X 2 X 2 = 128)
