We informally define the term corresponding element as follows: The first element and the last element of a list are correspondi

ng elements. Similarly, the second element and the second last element are corresponding elements. The third element and the third last element are corresponding elements -- and so on. Given that the variable a is associated with a list, write an expression for the corresponding element of a[i].

Answer:

a[i] = a[len(a) - i - 1]

Explanation:

Based on the definition of corresponding elements above,

First element of a list and last element are corresponding :

Using this :

Given a list defined as 'a'

First element of list is at index 0

Last element of a list is at index ; len(a) - 1

For a list containing 10 elements:

Second element corresponds to second to the last element

Second element is at index 1;

Second to the Last element is at index 8

(since indexing starts from 0)

Second element = a[1]

Second to the last element = a[len(a) - i - 1]

Hence,

a[i] = a[len(a) - i - 1]

What is the initial condition in this set of code?
marissa [1.9K]

Answer:An initial condition is an extra bit of information about a differential equation that tells you the value of the function at a particular point. Differential equations with initial conditions are commonly called initial value problems.

The video above uses the example

{

d

y

d

x

=

cos

(

x

)

y

(

0

)

=

−

1

to illustrate a simple initial value problem. Solving the differential equation without the initial condition gives you  

y

=

sin

(

x

)

+

C

.

Once you get the general solution, you can use the initial value to find a particular solution which satisfies the problem. In this case, plugging in  

0

for  

x

and  

−

1

for  

y

gives us  

−

1

=

C

, meaning that the particular solution must be  

y

=

sin

(

x

)

−

1

.

So the general way to solve initial value problems is: - First, find the general solution while ignoring the initial condition. - Then, use the initial condition to plug in values and find a particular solution.

Two additional things to keep in mind: First, the initial value doesn't necessarily have to just be  

y

-values. Higher-order equations might have an initial value for both  

y

and  

y

′

, for example.

Second, an initial value problem doesn't always have a unique solution. It's possible for an initial value problem to have multiple solutions, or even no solution at all.

Object-oriented systems have three general types of cohesion: _____, _____, and _____. A. method, class, inheritance B. method,
Verdich [7]

Answer:

D. method, class, generalization/specialization

Explanation:

The Cohesion is said to be the level to what an element of a module is related to others. Generally, the cohesion can be understood as an internal adhesive that holds together the modules. If the software is good then it is going to have high cohesion. Method and class are type of cohesion, as they hold the modules together. And generalization/specialization also is a general type of cohesion as generalization tracks the common features among the class, and binds them into one superclass. However, the specialization means creating subclasses out of the classes, and which is the meaning of the specialization. In an ideal situation, there should be high cohesion or single responsibility. However, in the case of inheritance, there can be multiple responsibilities. And hence composition like a generalization, specialization, association, aggregation are used to make use of the composition for reuse rather than inheritance. Have you seen language supporting multiple inheritances. You will never see it though there is some way. And its never allowed to ensure high cohesion. And hence three general types of cohesion are method, class and generalization/specialization. And this is option D.
