Answer:
&myints[1] == 0xbe4354
&myints[2] == 0xbe4358
Explanation:
Assuming that sizeof(int) == 4, add 4 bytes for every array element.
2.2-2 Consider sorting numbers stored in array by first finding the smallest element n A of and exchanging it with the element in . Then find the second smallest A AOE1 element of A, and exchange it with . Continue in this manner for the firs AOE2 1 elements of A. Write pseudocode for this algorithm, which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the firs elements, rather than for all elements? Give the best-case n 1 n and worst-case running times of selection sort in ‚-notation.
Answer:
Follows are the explanation of the choices:
Explanation:
Following are the Pseudocode for selection sort:
for j = 0 to k-1 do:
SS = i
For l = i + 1 to k-1 do:
If X(l) < X(SS)
SS= l
End-If
End-For
T = X(j)
X(j) = X(SS)
X(SS) = T
End-For
Following are the description of Loop invariants:
The subarray A[1..j−1] includes the lowest of the j−1 components, ordered into a non-decreasing order, only at beginning of the iteration of its outer for loop.
A[min] is the least amount in subarray A[j.. l−1] only at beginning of the each loop-inner iterations.
Following are the explanation for third question:
Throughout the final step, two elements were left to evaluate their algorithm. Its smaller in A[k-1] would be placed as well as the larger in A[k]. One last is the large and medium component of its sequence because most and the last two components an outer loop invariant has been filtered by the previous version. When we do this n times, its end is a repetitive, one element-sorting phase.
Following is the description of choosing best-case and worst-case in run- time:
The body the if has never been activated whenever the best case time is the list is resolved. This number of transactions are especially in comparison also as a procedure, that will be (n-1)(((n+2)/2)+4).
A structure iterator at every point in the worst case that array is reversed, that doubles its sequence of iterations in the inner loop, that is:(n−1)(n+6) Since both of them take timeΘ(n2).

#TODO: Define a data structure to keep track of which links are part of / not part of the spanning tree.
Answer:
A spanning tree is a subset of Graph G, which has all the vertices covered with minimum possible number of edges. Hence, a spanning tree does not have cycles and it cannot be disconnected.. By this definition, we can draw a conclusion that every connected and undirected Graph G has at least one spanning tree.
A computer has 38 address lines. How many locations in Mega bytes can it address?
Answer:
The computer can address 34359,738368 megabytes
Explanation:
Given
Address Lines (n) = 38
Required
Determine the number of location it can address
Number of addressable locations (N) in bits is calculated as thus
[tex]N = 2^n.[/tex]
Substitute 38 for n
[tex]N = 2^{38}[/tex]
[tex]N = 274877906944\ bits[/tex]
Next; is to convert from bits to megabytes
Start by converting to bytes
1 bit = 0.125 bytes;
So;
[tex]N = 274877906944 * 0.125\ bytes[/tex]
[tex]N = 34359738368\ bytes[/tex]
Convert from byte to megabyte
[tex]1\ byte = 10^{-6}\ megabyte[/tex]
So;
[tex]N = 34359738368\ * 10^{-6}\ MB[/tex]
[tex]N = 34359,738368\ MB[/tex]
Hence, the computer can address 34359,738368 megabytes

const double gallon = area/350.0;
cout<<"Paint needed: "<<gallon<<" gallons"<<"\n";
//3
cout << "Cans needed :" << round(gallon) << " can(s)";
return 0;
}
Explanation:
This line declares the height and width as double
double height, width;
This line prompts user for height
cout<<"Enter wall height (feet): ";
This line gets user input for height
cin>>height;
This line prompts user for width
cout<<"Enter wall width (feet): ";
This line gets user input for width
cin>>width;
//1 Question 1 begins here
This line declares area as double
double area;
The line calculates area
area = width * height;
The line prints the calculated area
cout<<"Wall area: "<<area<<" square feet"<<"\n";
//2 Question 2 begins here
This line declares and calculates gallon as a constant double variable
const double gallon = area/350.0;
This line prints the calculated gallon
cout<<"Paint needed: "<<gallon<<" gallons"<<"\n";
//3 Question 3 begins here
This line rounds gallon to nearest whole number and prints the result
cout << "Cans needed :" << round(gallon) << " can(s)";
