Recall the stack-based algorithm (where an opening brace or a parenthesis is pushed into the stack, and on encountering closing braces or parentheses, a pop is performed on the stack) for determining whether a sequence of parentheses is well formed or not (balanced). If the given string is: Then what is the maximum number of brackets that would appear in the stack at any instant? A bracket in this context can be any one of the following four types: '(', '{', '}' and ')'. The sequence can be either well formed or ill formed. a :2 b:3 C: 4 d:5

Implement a queue Q with two stacks S1 and S2, so that the stacks that operate together as a queue may perform the operations ENQUEUE(Q, X) and DEQUEUE(Q, Y), where Q appears to be a queue and X is the element to be inserted into Q and Y is the element to be removed from Q. Assume that the ADT operations PUSH, POP, and EMPTYSTACK are only available for stacks.Show how your technique works on a list a, b, c, which will be utilised as a queue by the stacks S1 and S2.
Implement a stack S with two queues Q1 and Q2 so that the operations PUSH (S, X) and POP(S, Y), where S is presumably a stack and X is the element to be added to S and Y is the element removed from S, are handled by the queues that function as a stack as a whole. Assume that only queues are accessible to ADT's ENQUEUE, DEQUEUE, and EMPTYQUEUE operations.Show how your function operates on a list of items (a, b, and c) that will be used as a stack by the queues Q1 and Q2.
Implement a queue Q using two stacks S1 and S2 such that operationsENQUEUE(Q, X) and DEQUEUE(Q, Y), where Q is supposedly a queue and X isthe element to be inserted into Q and Y the element deleted from Q, are workedupon by the stacks that operate together as a queue. Assume that the ADT operations of PUSH, POP and EMPTYSTACK are only available for the stacks. Demonstrate the working of your method on a list {a, b, c}, which is to beoperated upon as a queue by the stacks S1 and S2.

Implement a stack with a single queue so that each stackoperations takes a linear number of queue operations. Hint : To delete an item, get allof the elements on the queue one at a time, and put them at the end, except for the lastone which you should delete and return. (
There is a bag-like data structure, supporting two operations: 1 x1 x: Throw an element xx into the bag. 22: Take out an element from the bag. Given a sequence of operations with return values, you’re going to guess the data structure. It is a stack (Last-In, First-Out), a queue (First-In, First-Out), a priority-queue (Always take out larger elements first) or something else that you can hardly imagine! Input There are several test cases. Each test case begins with a line containing a single integer nn (1≤n≤10001≤n≤1000). Each of the next nn lines is either a type-1 command, or an integer 22 followed by an integer xx. This means that executing the type-2 command returned the element xx. The value of xx is always a positive integer not larger than 100100. The input is terminated by end-of-file (EOF). The size of input file does not exceed 1MB. Output For each test case, output one of the following: stackIt’s definitely a stack. queueIt’s definitely a queue. priority queueIt’s definitely…
Implement a queue with three stacks so that, in the worst-case scenario, each queue operation requires a fixed number of stack operations. High level of difficulty alert.
What is the time complexity of pushing and popping items to/from a stack containing n items, respectively? What is the time complexity of dequeue and enqueue operations on a FIFO queue containing n itmes, respectively?Suppose you push 1, 4, 7, and 10 onto the stack. Then you pop two times. Then add 3 to the number at the top and push the sum to the stack. Which are the numbers left on the stack? (write from bottom to the top). As other items are inserted and removed, does a particular item in a queue move along the array from lower to higher indices, or higher to lower, or not move?
Implement a nonrecursive version of quicksort basedon a main loop where a subarray is popped from a stack to be partitioned, and the resulting subarrays are pushed onto the stack. Note : Push the larger of the subarrays ontothe stack first, which guarantees that the stack will have at most lg N entries.
Show how to replace the related stack with a single reference in an in-order traversal by removing the accompanying stack. (Hint: The items below the stack top are decided by the stack top; we just need to know the top of the stack.) 12.23 Which additional traversals can be reformulated by substituting a single reference for their Linear structure? How does this modification affect how complicated each iteration is?
There is a data structure called a drop-out stack that behaveslike a stack in every respect except that if the stack size is n,then when the n+1 element is pushed, the first element is lost.Implement a drop-out stack using links
