Reflection is the bouncing back of light when it strikes the smooth surface. Refraction is the bending of light when it travels from one medium to another .

Refraction represents a change in the direction of propagation when beams of light encounter a medium with a different density.

Reflection is the return of light to the medium it came from when it encounters a mirror.

4. When you're working with a word processing document and you press the Del key, what happens?
Thepotemich [5.8K]
When you're working with a word processing document and you press the Del key, C. The entire document is deleted.

I have actually tried doing this to know which choice is the correct answer. I opened a new document, typed some words then pressed the Del key.... NOTHING HAPPENED! The character to the right of the cursor was not deleted, the entire document was not deleted, nor was the formatting style deleted.

I chose letter C because after seeing that nothing happened in an open document, I saved said document and opened the folder where the document was saved. I selected the document and pressed the Del key... a prompt appeared asking me if I was sure that I want to move my file to the Recycle Bin? I clicked yes... the entire document is deleted

Give an O(log m + log n)-time algorithm that takes two sorted lists of sizes m and n, respectively, as input and returns the ith
olga2289 [7]

Binary search is used similarly. K'th element is found in more productive way.

<u>Explanation:</u>

arr1 and arr2 are the middle elements which are compared, let us compute as mid1 and mid2. Let us predict arr1 [mid1] k, the elements are not needed after mid2 elements.  arr2 are set as last element for arr2 [mid2].  New sub problems are defined. When one array is half the size.

C++ code for the algorithm.

#include <iostream>

using namespace std;    

int kth(int *arr1, int *arr2, int *end1, int *end2, int k)

{

if (arr1 == end1)

return arr2[k];

if (arr2 == end2)

return arr1[k];

int mid1 = (end1 - arr1) / 2;

int mid2 = (end2 - arr2) / 2;

if (mid1 + mid2 < k)

{

if (arr1[mid1] > arr2[mid2])

return kth(arr1, arr2 + mid2 + 1, end1, end2,

k - mid2 - 1);

else

return kth(arr1 + mid1 + 1, arr2, end1, end2,

k - mid1 - 1);

}

else

{

if (arr1[mid1] > arr2[mid2])

return kth(arr1, arr2, arr1 + mid1, end2, k);

else

return kth(arr1, arr2, end1, arr2 + mid2, k);

}    

int main()

{

int arr1[5] = {2, 3, 6, 7, 9};

int arr2[4] = {1, 4, 8, 10};    

int k = 5;

cout << kth(arr1, arr2, arr1 + 5, arr2 + 4, k - 1);

return 0;

}
