A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. Define a predicate isSorted that expects a list as an argument and returns True if the list is sorted, or returns False otherwise. (Hint: For a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return False if the first item in a pair is greater.)

Problems on amortized analysis

Amortized analysis is a technique used to perform micro-level analysis of an algorithm's complexity or resource (time and memory) consumption. It is used for analyzing the time efficiency of data structures that support many operations such as stacks and heaps.Operations supported by stack include push, pop, multi push, and multi pop while operations supported by heap are inserted, delete, extract-min, and so forth. It focuses on the sequence in which these operations are executed and therefore, provides an accurate cost estimation.

Question

A list is sorted in ascending order if it is empty or each item except the last
one is less than or equal to its successor. Define a predicate isSorted
that expects a list as an argument and returns True if the list is sorted, or
returns False otherwise.
(Hint: For a list of length 2 or greater, loop through the list and compare
pairs of items, from left to right, and return False if the first item in a pair is
greater.)
Below is an example of a main function and the associated output:
def main():
lyst =
print(isSorted(lyst))
lyst = [1]
print(isSorted(lyst))
lyst = list(range(10))
print(isSorted(lyst))
lyst[9] = 3
print(isSorted(lyst))

Programming homework1) Simulated waiting queue in an Indian post office: In an Indian post office that not only distributes mail but also performs some financial activities like a savings bank, a lone postal worker attends to a single lineup of clients. As soon as a consumer enters the line, they are given a token # (serial number). After receiving assistance, the consumer exits the queue while the postal worker receives the token back. The employee could inquire as to how many consumers are still unattended at any one time.i) Put the system into practise using a suitable queue data structure, simulating the arrival and departure of consumers at random when the service is finished.

Presentation exercise 2 Write a function (including docstring) called multiply_term that takes a polynomial as inputs and a term. We can represent polynomials as a collection or power-coefficient pairs. Consider the following polynomial: p(x) = 2 - a4 – 3. x+ 5. We can represent it as the following collection of pairs: (4, 2), (1, -3), (0, 5). We can represent a term as a tuple where the first value indicated the exponent in the term, and the second its coefficient. For example, the term 5 - a* is represented by the tuple (4, 5). The function does not return anything, but after its execution the input dictionary will now represent the multiplication of the input polynomial by the specified term. For example: Page 2 >> p = {2 : 1, 1 : 2} # x^2 + 2x >>> t = (4, 5) # 5x^4 >>> multiply_term(p, t) >>> p == {6 : 5, 5 10} True You can assume that the function will receive as input a dictionary mapping integers to numbers. No need for you to implement any type of input validation.
