- A 2-dimensional Turing machine has an infinite 2-dimensional grid asits storage device (one cell for every address (i, j) ∈Z×Z). Instead ofL and R, there are 5 options for the head to move from (i, j): Left (to(i −1, j), Right (to (i + 1, j)), Up (to (i, j + 1)), Down (to (i, j −1)),and Stay (remain at (i, j)) .Let us assume, that our 2-dimensional TM M has an additional 1-dimensional tape where the input is located as in a 1-tape TM. The2-dimensional storage device contains a blank symbol in every cell atthe start of the computation.Show that a 2-dimensional TM is not more powerful, i.e., every lan-guage accepted by a 2-dimensional TM M is accepted by one of ourstandard 1-dimensional TMs. You don’t have to simulate directly witha 1-tape TM, as you are allowed to use what we know about k-tape(1-dimensional) TMs without proof.Describe the moves of a simulating TM M ′ in plain English.

In this setting, show how the algorithm can be altered so that it only needs min(m,n) + O(1) space rather than m · n space (note that it must be min(m,n) and not O(min(m, n))).arrow_forwardDetermine whether there is a feasible schedule for the following set of periodic processes.

- Implement this algorithm in C program . Show the gantt chart as output. Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing.
