Turing Machine − A Turing machine is a device used to accept words of a language generated by type 0 grammars. A Turing Machine (TM) is a mathematical model which consists of an infinite length tape divided into cells on which input is given. It consists of a head which reads the input tape. A state register stores the state of the Turing machine. After reading an input symbol, it is replaced with another symbol, its internal state is changed, and it moves from one cell to the right or left. If the TM reaches the final state, the input ...

We are given with a matrix of numbers. The goal is to find the number of Magic squares present inside the given matrix.A Magic Square, if taken as a matrix, is a 3X3 matrix which contains the elements ranging from 1 to 9 just like a grid in Sudoku. Properties are −All numbers occur exactly once.Sum of all 9 cells in the matrix is 45.Sum of each row of 3 is 15.Sum of each column of 3 is 15.Sum of diagonals of 3 is 5.To get such sums, 5 is always in the middle of both diagonals.Inputint arr[][]= { { ...
