enqueue and dequeue operations. The enqueue operations put the integers 0 through

Suppose that a client performs an intermixed sequence of Queue enqueue and dequeue operations. The enqueue operations put the integers 0 through 9 in order onto the Stack; each dequeue operation pops the top item off the Stack and prints the returned value. Determine if each of the following sequences can or cannot be a result of some sequence of the operations described above. If the sequence is possible, give a sequence of operations that will give that result. If the sequence is not possible, explain why not. (a) 3 2 1 0 4 5 69 87 (b)3 2 5 4 7 6 1 9 8 0 (C) 0 31 25 6 4 7 8 9 Write pseudocode for an algorithm that uses a Stack to determine if a String of characters containing parentheses is properly balanced. Examples: Input: (x + (y - 7) * 6) Output: true Input: (00) Output: true Input: ((asdf)(qwerty) Output: false
