5. (12 points) Design PDAs for the following languages. For cach language, you are asked to first give an informal description of your PDA and then give the state diagram. (a) {01/0 |i,j1} (b) {abick | i-jor j = k, where i, j, k 0}. Note that this is not the same language as that in Question 3(c). 6.
