Please answer in Pseudocode.
Once we have a method for checking one column, we can use the following function to check all columns:
function ColChecks(puzzle)
for 1 j 4 do
if CheckColumn(puzzle, j) = FALSE then
return FALSE
end if
end for
return TRUE
end function
The next set of conditions to check is to see if all integers from 1 to 4 appear in the 2-by-2 sub-grids. In the next task, the goal is to replicate the approach of the function CheckColumn but for these sub-grids. In the function you should repeatedly call SearchStack for each element in a sub-grid, and then do this for all four sub-grids.
Task 6: Complete the following function:
function CheckGrids(puzzle)
...
end function
This function will take the vector puzzle (as produced by MakeVector) as an input parameter and check that all sub-grids contain all numbers from 1 to 4: if every sub-grid does contain all numbers from 1 to 4, it should return TRUE, otherwise it should return FALSE. For each sub-grid you should create a stack with numbers from 1 to 4, and then repeatedly search the stack to see if the values in the sub-grid are stored there. To get full marks you need to call SearchStack(stack, item).
