 #### Get Bit
 
-This method shifts the relevant bit to the zeroth position.  Then we perform 'AND' operation with one which has bit pattern like '00001'.  This clears all bits from the original number except the relevant one.  If the relevant bit is one, the result is '1', otherwise the result is '0'.
