PSPACE is defined as the class of languages for which there exists a deterministic TM

decider that uses at most polynomial amount of space with respect to the size of the input.

Show that PSPACE is closed under the operations concatenation, complementation, and

star. For each case, compute a decidable Turing Machine and prove its correctness. PLEASE BE RIGOROUS AND THOROUGH WITH THE ALGORITHM YOU PROVIDE. THUMBS UP WILL BE GIVEN TO CORRECT ANSWERS
