Please answer in Pseudocode function CheckGrids(puzzle) for i=1 to 4 do stack =[1,2,3,4] for j=(i1)4+1 to i4 do item = puzzle[j] if ISearchStack(stack, item) then return FALSE end if end for end for return TRUE end function function IsSudokuValid(puzzle) if !CheckRows(puzzle) then return FALSE end if if !CheckColumns(puzzle) then return FALSE end if if !CheckGrids(puzzle) then return FALSE end if return TRUE end function Please answer in Pseudocode Analysing the algorithm The goal is to analyse the algorithm in the above functions. The algorithm to generate Pseudoku puzzles outlined here might not produce all possibly valid Pseudoku puzzles. Remember that, generally speaking, the algorithm works by cyclically permuting several rows of a vector until the Pseudoku conditions are satisfied. In this task you should aim to identify all of the weaknesses you can think of in this algorithm. Task 10: Describe and very briefly explain the limitations of the algorithm in this assignment. Maximum word count for the whole task: 400 words (excluding figures). [6 marks] Please answer TASK 10 by referring the above functions. Please answer in Pseudocode
