Initially on the blackboard eight zeros are written. In one step, it is allowed to choose numbers a,b,c,da,b,c,d, erase them and replace them with the numbers a+1a+1, b+2b+2, c+3c+3, d+3d+3. Determine: a) the minimum number of steps required to achieve 88 consecutive integers on the board b) whether it is possible to achieve that sum of the numbers is 20212021 c) whether it is possible to achieve that product of the numbers is 21452145
