Professor Gekko has always dreamed of inline skating across North Dakota. He plans to cross the state on highway U.S. 2, which runs from Grand Forks, on the eastern border with Minnesota, to Williston, near the western border with Montana. The professor can carry two liters of water, and he can skate m miles before running out of water. (Because North Dakota is relatively flat, the professor does not have to worry about drinking water at a greater rate on uphill sections than on flat or downhill sections.) The professor will start in Grand Forks with two full liters of water. His official North Dakota state map shows all the places along U.S. 2 at which he can refill his water and the distances between these locations. The professor’s goal is to minimize the number of water stops along his route across the state.

a. Give an efficient algorithm by which he can determine which water stops he should make.

b. Prove that your strategy yields an optimal solution, and give its

Answers

Answer 1

The efficient algorithm by which he can determine which water stops he should make; has been determined below and the strategy which is the greedy strategy has been proven to yield an optimal solution.

To solve this question optimally, we will make use of the greedy solution.

In this method, we will maximize the distance that can be covered from a particular point in such a way that there must be a place where water can be gotten before a run out is experienced.

Now, the first point at which there will be a stop should be located at a point that is farthest from the starting position and is also made to be ≤ m miles from the starting position.

Now, this this situation is one that shows optimal substructure and since our  first stopping point will be made to be at p, it means that we are solving the sub-question with the assumption that our starting point is at p.

When we combine the two stated plans above, we will arrive at an optimal solution for the normal reasons via cut and paste.

B) Now we need to show that the greedy approach earlier used produce a first stopping point which is contained in the optimal solution.

Let O represent any optimal solution whereby the professor stops at positions o₁, o₂, o₃....oₙ.

Let h₁ represent the farthest stopping point that is reachable from the starting point. Then we can replace o₁ by h₂ to generate a modified solution H since o₁ - o₂ < o₂ - h₁.

Finally, we can really make it to the positions in H without having to run out of water and since H has the same number of stops, we can conclude that h₁   is contained in one of optimal solution.

Therefore our strategy which is the greedy strategy has been proven to work.

What is Invoice Delayed Credit?

A delayed credit is a non-posting transaction that you can add to a client's invoice at a later time.

Reimbursing a customer's money involves posting a transaction known as a refund. The use of credit notes to reduce an outstanding customer amount follows from this. Delayed Credits are only permitted on invoices.

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. Nested lists The “*” operator List slices The “+=” operator A list filter A list operation that is legal but does the "wrong" thing, not what the programmer expects Provide the Python code and output for your program and all your examples.

Answers

Lists are used in Python to hold multiple values in one variable

(a) Nested list

A nested list is simply a list of list; i.e. a list that contains another list.

It is also called a 2 dimensional list.

An example is:

nested_list = [[ 1, 2, 3, 4]  , [ 5, 6, 7]]

(b) The “*” operator

The "*" operator is used to calculate the product of numerical values.

An example is:

num1 = num2 * num3

List slices

This is used to get some parts of a list; it is done using the ":" sign

Take for instance, you want to get the elements from the 3rd to the 5th index of a list

An example is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

secondList = firstList[2:5]

The “+=” operator

This is used to add and assign values to variables

An example is:

num1 = 5

num2 = 3

num2 += num1

A list filter

This is used to return some elements of a list based on certain condition called filter.

An example that prints the even elements of a list is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

print(list(filter(lambda x: x % 2 == 0, firstList)))

A valid but wrong list operation

The following operation is to return a single list, but instead it returns as many lists as possible

def oneList(x, myList=[]):

   myList.append(x)

   print(myList)

oneList(3)

oneList(4)

how to count binary ? Help Better understand this question

Answers

Explanation:

For each row in the picture, you have to switch on some of the bits to create the number on the left.

Each bit has a value, a "weight" so to speak. By switching on the bit, you add that weight to the sum.

These "weights" are shown at the top row.

So to create 4, it's easy, you just switch on the '4' bit.

Same for 128, only one bit has to be switched on.

40 is a bit more involved, now you have to switch on 32 and 8, since 32+8 is 40.

For every number, there is exactly one combination of switched on bits to create that number. In the case of 40, the binary representation is:

00101000.

Answers

Answer:

0

Explanation:
In the lists, indexation starts from 0, because of that in if statement we compare item[0] which is 'male' and 'male', and then males is itterated within for loop.

Three steps can be taken to construct a list of elements using a for loop: Make an empty list appear. Iterate through an iterable or set of elements. Add each component to the list's end.

What loop for sample member of the list data?

An Array List can be looped through using an Iterator. If there are additional members in the Array List, the method hasNext() returns true; otherwise, it returns false. If there is no next element, the method next() raises the No Such Element Exception and returns the next element in the Array List.

FOR LOOPS and WHILE LOOPS are two popular types of loops. A For loop runs a variable number of times. LOOP TYPE — FOR LOOP When you know how many times you want to run an algorithm before stopping, you use for loops.

Therefore, Since indexation in lists begins at 0, we must compare item[0], which is “male,” with “male” in the if statement before iterating through males in the for loop.
