Answer: The correct answer is to hover the cursor over the different styles in the gallery.
Explanation: The fastest way to preview the different styles in the style gallery is to hover the cursor over each style. This will preview the style, without making the permanent change so that you can see how it looks without changing to each individual style.
Answer:
li=list(map(str,input().strip().split()))#taking input of the string.
#swapping first and last element.
temp=li[0]
li[0]=li[-1]
li[-1]=temp
print(li)#printing the list.
Explanation:
I have taken the list li for taking the input of strings.Then after that swapping first and last element of the list.Then printing the list.
Answer:
public: virtual void print()=0;
Explanation:
An abstract class contains a pure virtual function. Pure virtual class cannot be instantiated but it can be subclassed and the subclass can provide an implementation of the function.
A virtual function declaration in the class is preceded by the virtual keyword. For example, virtual void print();
A pure virtual function declaration is followed by '=0;'
public: virtual void print()=0;
Answer:
The correct answer to the following question will be "Adaptive Optics".
Explanation:
- AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
- It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.
- It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.
- Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.
Therefore, Adaptive Optics is the right answer.
