The basic overview of steps involved in a solution of a rubik's cube

Download the library to be used : Link 1

To link this library to your code use these steps : watch from 1:41 Youtube

Here is the basic layout of the cube

We can see that every step is in form of rotation of one of six faces in either clockwise or anti-clockwise direction relative to the face and we have defined functions for the same

Basic overview of functioning of library

We are imagining the cube as a 6x3x3 matrix which hold values according to the above layout

Using the library functions

First we need to create a 6x3x3 matrix like this :

int cube[6][3][3]= {{{11, 12, 13}, {14, 15, 16}, {17, 18, 19}}, {{21, 22, 23}, {24, 25, 26}, {27, 28, 29}}, {{31, 32, 33}, {34, 35, 36}, {37, 38, 39}}, {{41, 42, 43}, {44, 45, 46}, {47, 48, 49}}, {{51, 52, 53}, {54, 55, 56}, {57, 58, 59}}, {{61, 62, 63}, {64, 65, 66}, {67, 68, 69}}};

We can(should) change the values depending on how we have scrambled the cube

To rotate one face clockwise we use the following statement : face1(&cube[0][0][0], 0) // this rotates the face1 clockwise ie. the white face

List of functions

function name	work
face1(int *a, int b)	rotates white face
face2(int *a, int b)	rotates red face
face3(int *a, int b)	rotates green face
face4(int *a, int b)	rotates orange face
face5(int *a, int b)	rotates blue face
face6(int *a, int b)	rotates yellow face

First parameter tells the address first element of the face

Second tells if rotation is clockwise or anti-clockwise

0 for clockwise

1 for anti-clockwise
