* Problem 103
*
* Let S(A) represent the sum of elements in set A of size n. We shall
* call it a special sum set if for any two non-empty disjoint subsets,
* B and C, the following properties are true:
*
* i) S(B) != S(C); that is, sums of subsets cannot be equal.
* ii) If B contains more elements than C then S(B) > S(C).
*
* If S(A) is minimised for a given n, we shall call it an optimum
* special sum set. The first five optimum special sum sets are given
* below.
*
* n = 1: {1}
* n = 2: {1, 2}
* n = 3: {2, 3, 4}
* n = 4: {3, 5, 6, 7}
* n = 5: {6, 9, 11, 12, 13}
*
* It _seems_ that for a given optimum set, A = {a_1, a_2, ..., a_n},
* the next optimum set is of the form B = {b, a_1+b, a2+b, ... a_n+b},
* where b is the "middle" element on the previous row.
*
* By applying this "rule" we would expect the optimum set for n = 6 to
* be A = {11, 17, 20, 22, 23, 24}, with S(A) = 117. However, this is
* not the optimum set, as we have merely applied an algorithm to
* provide a near optimum set. The optimum set for n = 6 is A = {11,
* 18, 19, 20, 22, 25}, with S(A) = 115 and corresponding set string:
* 111819202225.
*
* Given that A is an optimum special sum set for n = 7, find its set
* string.
*
* NOTE: This problem is related to problems 105 and 106.

Sum square difference Problem 6
The sum of the squares of the first ten natural numbers is,
1^2 + 2^2 + ... + 10^2 = 385
The square of the sum of the first ten natural numbers is,
(1 + 2 + ... + 10)^2 = 55^2 = 3025
Hence the difference between the sum of the squares of the first ten natural
numbers and the square of the sum is 3025 − 385 = 2640.
Find the difference between the sum of the squares of the first one hundred
natural numbers and the square of the sum.
answer is 25164150
------------------------------------
*************************************************************************
ideas :-
1) 1+2+3+..n = n(n+1)/2
2) 1^2 + 2^ +.....+n^2 = n(n+1)(2n+1)/6
thats it we are ready to solve this Problem :)

** Name: brcm_patchram_plus.c

** <--scopcm=sco_routing,pcm_interface_rate,frame_type,
** sync_mode,clock_mode,lsb_first,fill_bits,
** fill_method,fill_num,right_justify>
**
** Where
**
** sco_routing is 0 for PCM, 1 for Transport,
** 2 for Codec and 3 for I2S,
**
** pcm_interface_rate is 0 for 128KBps, 1 for
** 256 KBps, 2 for 512KBps, 3 for 1024KBps,
** and 4 for 2048Kbps,
**
** frame_type is 0 for short and 1 for long,
**
** sync_mode is 0 for slave and 1 for master,
**
** clock_mode is 0 for slabe and 1 for master,
**
** lsb_first is 0 for false aand 1 for true,
**
** fill_bits is the value in decimal for unused bits,
**
** fill_method is 0 for 0's and 1 for 1's, 2 for
** signed and 3 for programmable,
**
** fill_num is the number or bits to fill,
**
** right_justify is 0 for false and 1 for true
**
** <--i2s=i2s_enable,is_master,sample_rate,clock_rate>
**
** Where
**
** i2s_enable is 0 for disable and 1 for enable,

** is_master is 0 for slave and 1 for master,
**
** sample_rate is 0 for 8KHz, 1 for 16Khz and
** 2 for 4 KHz,
**
** clock_rate is 0 for 128KHz, 1 for 256KHz, 3 for
** 1024 KHz and 4 for 2048 KHz.
**
** <--no2bytes skips waiting for two byte confirmation
** before starting patchram download. Newer chips
** do not generate these two bytes.>
** <--tosleep=number of microsseconds to sleep before
** patchram download begins.>
** uart_device_name
**
** For example:
**
** brcm_patchram_plus -d --patchram \
** BCM2045B2_002.002.011.0348.0349.hcd /dev/ttyHS0
**
** It will return 0 for success and a number greater than 0
** for any errors.
**
** For Android, this program invoked using a
** "system(2)" call from the beginning of the bt_enable
** function inside the file
** system/bluetooth/bluedroid/bluetooth.c.
**
** If the Android system property "ro.bt.bcm_bdaddr_path" is
** set, then the bd_addr will be read from this path.
** This is overridden by --bd_addr on the command line.
